He has averaged exactly 100 pitches per start if we throw out the two starts that ended for reasons beyond his control. He continues to have one of the longest leashes in baseball as well. Ohtani gets a great matchup today as the Pirates rank fifth-worst in the league in both wOBA (.300) and wRC+ (86) versus right-handed pitching. See sign up bonuses from the best baseball betting sites.Two of the other nine starts ended prematurely (one due to a blister and another due to a rain delay). He has recorded more than 7.5 strikeouts in 9 of his 18 starts this season. His 32.2% strikeout rate ranks third best in the league among qualified starting pitchers. We will focus on the pitching side today as Ohtani will make his 19th start of the season against the Pirates. Ohtani is putting together yet another phenomenal season both at the dish and on the mound. Shohei Ohtani Getty Images Shohei Ohtani more than 7.5 Pitcher Strikeouts I think Oviedo falls short of this projection today. Their projected lineup contains just two hitters that have struck out more than 25% of the time this season. They rank fifth in the league in both wOBA (.336) and wRC+ (113) versus righties. Today, he gets a matchup with the Angels who have been excellent versus right-handed pitching this season. Oviedo has thrown more than 6 strikeouts in just two of his other 18 starts this season. This projection feels slightly inflated because he is coming off of a 10-strikeout masterpiece his last time out against the Giants. However, his strikeout rate checks in slightly below league average at 20.4%. He owns a 4.53 ERA that is supported by underlying metrics such as xFIP (4.56) and SIERA (4.63). Oviedo has been right around league average as a starting pitcher this season. Johan Oviedo less than 6.0 Pitcher Strikeouts The tough matchup, the manager’s quick hook for his starting pitchers, and a strikeout rate below 19% are all working against Gonsolin today. Gonsolin has failed to record at least 4 strikeouts in three of his last four starts. The Rangers own the league’s top wRC+ at 122, and they also rank second in wOBA at. Tony Gonsolin Getty Imagesįast forward to today’s matchup, where Gonsolin will meet up with one of baseball’s best offenses in Arlington, Texas. These shenanigans are nothing new for Roberts and the way he handles his pitching staff, especially with Gonsolin who has averaged just 68 pitches per start in his last 4 starts. Manager Dave Roberts blamed the quick hook for Gonsolin on the “humidity” and the fact he had a “fresh ‘pen” in that particular game. He was yanked after just 54 pitches in his last outing despite cruising through 5 innings and allowing only 1 run. Gonsolin has one of the shortest leashes of any regular starting pitcher in the league. Tony Gonsolin less than 4.0 Pitcher Strikeouts Lugo has thrown over 90 pitches in each of his last three starts and should have enough leash to get the job done for us tonight.

Boeing, Douglas, and Lockheed were given additional study contracts for the airframe, along with General Electric and Pratt & Whitney for the engines. In May 1964, airframe proposals arrived from Boeing, Douglas, General Dynamics, Lockheed, and Martin Marietta engine proposals were submitted by General Electric, Curtiss-Wright, and Pratt & Whitney. The desire to keep the number of engines to four required new engine designs with greatly increased power and better fuel economy. The payload bay had to be 17 feet (5.18 m) wide by 13.5 feet (4.11 m) high and 100 feet (30 m) long with access through doors at the front and rear. These studies led to initial requirements for the CX-Heavy Logistics System (CX-HLS) in March 1964 for an aircraft with a load capacity of 180,000 pounds (81.6 t) and a speed of Mach 0.75 (430 kn 800 km/h), and an unrefueled range of 5,000 nautical miles (9,300 km 5,800 mi) with a payload of 115,000 pounds (52.2 t). Although the C-141 Starlifter was being introduced, officials believed that a much larger and more capable aircraft was needed, especially to carry cargo that would not fit in any existing aircraft. In 1963, the United States Air Force started a series of study projects on a very large strategic transport aircraft. The final 747 was delivered to Atlas Air in January 2023 after a 54-year production run, with 1,574 aircraft built.Īs of January 2023, 64 Boeing 747s (4.1%) have been lost in accidents and incidents, in which a total of 3,746 people have died.ĭevelopment Background Cargo nose door open with cargo loader Freighter variants of the 747 remain popular with cargo airlines. Airbus competed with later variants with the heaviest versions of the A340 until surpassing the 747 in size with the A380, delivered between 20. Initial competition came from the smaller trijet widebodies: the Lockheed L-1011 (introduced in 1972), McDonnell Douglas DC-10 (1971) and later MD-11 (1990). The 747 is the basis for several government and military variants, such as the VC-25 ( Air Force One), E-4 Emergency Airborne Command Post, Shuttle Carrier Aircraft, and some experimental testbeds such as the YAL-1 and SOFIA airborne observatory. After several studies, the stretched 747-8 was launched on November 14, 2005, with new General Electric GEnx engines, and was first delivered in October 2011. The heavier 747-400 with improved RB211 and CF6 engines or the new PW4000 engine (the JT9D successor), and a two-crew glass cockpit, was introduced in 1989 and is the most common variant. It was shortened for the longer-range 747SP in 1976, and the 747-300 followed in 1983 with a stretched upper deck for up to 400 seats in three classes. The partial double-deck aircraft was designed with a raised cockpit so it could be converted to a freighter airplane by installing a front cargo door, as it was initially thought that it would eventually be superseded by supersonic transports.īoeing introduced the -200 in 1971, with more powerful engines for a heavier maximum takeoff weight (MTOW) of 833,000 pounds (378 t) from the initial 735,000 pounds (333 t), increasing the maximum range from 4,620 to 6,560 nautical miles (8,560 to 12,150 km 5,320 to 7,550 mi). It has a pronounced 37.5° wing sweep, allowing a Mach 0.85 (490 kn 900 km/h) cruise speed, and its heavy weight is supported by four main landing gear legs, each with a four-wheel bogie. With a ten-abreast economy seating, it typically accommodates 366 passengers in three travel classes. The 747 is a four-engined jet aircraft, initially powered by Pratt & Whitney JT9D turbofan engines, then General Electric CF6 and Rolls-Royce RB211 engines for the original variants. The 747 was the first airplane called a "Jumbo Jet" as the first wide-body airliner. It entered service with Pan Am on January 22, 1970. The first flight took place on February 9, 1969, and the 747 was certified in December of that year. On September 30, 1968, the first 747 was rolled out of the custom-built Everett Plant, the world's largest building by volume. In April 1966, Pan Am ordered 25 Boeing 747-100 aircraft, and in late 1966, Pratt & Whitney agreed to develop the JT9D engine, a high-bypass turbofan. In 1965, Joe Sutter left the 737 development program to design the 747, the first twin-aisle airliner. The Boeing 747 is a large, long-range wide-body airliner designed and manufactured by Boeing Commercial Airplanes in the United States between 19.Īfter introducing the 707 in October 1958, Pan Am wanted a jet 2 + 1⁄ 2 times its size, to reduce its seat cost by 30%. 9/27/2023 0 Comments Kaleidoscope abelia pruningWhat tools should you use for pruning abelia kaleidoscope, and how should you sterilize them?

So we can rephrase the question with y ‘ = t(2 – y). Just substitute y for f( t) to make it easier to work with. Here, the step size is h = 0.5, so there will only be two new time values before landing on the goal time t = 1: Use Euler’s Method with step size 0.5 to estimate the value of f(1). nįinally, we see that our final answer is: y(1) = y 4 = 6.586. Now remember, the derivative is given you you: y ‘ = 3 y – 1. Note, here we are using x instead of t because sometimes the AP Calculus question will be in terms of x and y rather than t and y.īecause the step size is 0.25, we use x n = x 0 + nh to get: The equation y(0) = 1 means that the initial time is x 0 = 0 and initial value is y 0 = 1. The first clue is in the given information. Use Euler’s Method with h = 0.25 to estimate y(1) if y ‘ = 3 y – 1 and y(0) = 1. Let’s get to the examples! Example 1 - Getting the Basics Down Instead, if you have to solve a differential equation or initial value problem, then try using methods like separation of variables or in the simplest cases, integration (for a refresher, take a look at: AP Calculus Exam Review: Integrals). Unless the directions specify to use Euler’s Method, do not use it! It’s important to realize that this method does not give exact answers - just good estimates. One clue ( y-value) leads you to the next. Using Euler’s Method is like detective work. On the other hand, why stop at just one step? Once you know the value of y 1, then you can use that value in a similar way to find out y 2. If you’re only going from t 0 to t 1 (a single step), then you get: That means that you can replace y ‘ by its current value as determined by the function f. The final piece of the puzzle is to use the given information that y ‘ = f( t, y). Letting the difference in time be h = t 1 – t 0, then the formula becomes: Now if y changes from y 0 to y 1 in the time interval from t 0 to t 1, then we can express this fact using the derivative: So even if you don’t know what y is, if you can tell how fast it’s changing, then that info can help you to build up the values of y. The key is that the y ‘ always measures the rate of change of the function y. In fact, a good grasp of the theory helps you in other areas of calculus as well. It’s helpful to understand a little of the theory behind Euler’s Method. Then the solution at later times t 1, t 2, t 3, … can be found using the following algorithm. The given time t 0 is the initial time, and the corresponding y 0 is the initial value.įirst, you must choose a small step size h (which is almost always given in the problem statement on the AP exam). Euler’s MethodĮuler’s Method is a step-based method for approximating the solution to an initial value problem of the following type. What is Euler’s Method? In this post we review this technique for approximating solutions to certain kinds of differential equations and work out a few examples based on what you may see on the AP Calculus BC exam. |
