Create an algorithm to determine whether a given Mach number (actual speed divided by the speed of sound) is subsonic, transonic, supersonic, or hypersonic. Assume the user will enter the speed of the object in meters per second, and the program will calculate the Mach number and determine the appropriate Mach category. As output, the program will display the Mach category. The algorithm should include a check to ensure the user entered a positive value. If a nonpositive value is entered, the program should warn the user and terminate. The speed of sound is about 343 m/s. The classifications are as follows:
Subsonic < Mach 1
Transonic = Mach 1
Mach 1 < Supersonic < Mach 5
Hypersonic ≥ Mach 5

Thinking Like an Engineer: An Active Learning Approach (4th Edition)
- Scenario You are assigned a role as a mechanical engineer for a vehicle design manufacturing company. Your department has a software to perform numerical differentiation and integration. To be able to verify the results of using the software and validate these results, your department manager has asked you to analytically perform some tasks to validate the results generated by the software. Q: is the last two digits of your student Id number. If your number is (20110092) then Q=92. P: is the last digit of your student Id Number. If your number is (20110092) then P=2, If that digit equals zero then use P=1. Example: If your number is (20110040) then P=1. Task 1 Determine the gradient of following functions at the given points: a) x(t) = (2t7 + P t-2)² + (6vi – 5) when t = 1 5s+7 b) v(s) = when s = 3 (s²-P)2 c) i(t) = 5(1 – In(2t – 1) ) when t= 1 sec. d) V(t) =5sin(100nt + 0.2) Volts , find i(t) = 10 × x10-6 dV©) Ampere when t= 1ms. dt e) y(t) = e¬(t-n) sin(Qt + P) when t = n radian f)…arrow_forwardMy professor said that I need to use the numbers as shown on the picture and make the exact graph that is also shown on the picture.

- Please provide equations that you are using so I can follow along and learn how to do this and include conversions and units. In Jamestown, NY, a coal power plan consumes coal at a rate of 80 tons/hr. When coal burns, it generates approximately 30,000 kJ for every kg of coal burned. The cooling course for the plant is the nearby Chadakoin River nearby and, by code, the power plant cannot reject more than 13.19 x 109 MJ into the river annually. Determine the maximum average power output of this plant and it's maximum thermal efficiency. To check your work, enter the efficiency, as a decimal, in the box provided.arrow_forward3:04 7 This question is a long free-response question. Show your work for each part of the question. Cylindrical Object Incline Figure 1 A cylindrical object can roll down an incline, as shown in Figure 1. The incline is slightly less than one meter in length. A group of students wants to determine the acceleration of the object while it is rolling down the incline. The students have access to the following equipment. · A stopwatch, which can measure time intervals up to 999 s with a precision of 0.01 s · A clock, which can measure time intervals up to 12 hours with a precision of 1 min ute (60 s) • A meterstick, which can measure lengths up to 1 m with a precision of 1 mm · A pair of calipers, which can measure lengths up to 10 cm with a precision of 0.05 mm (a) Assume the object moves with a constant acceleration as it rolls down the incline.

- 4:16 Search Expert Q&A Done Please solve question 16-109 below this in the follwoing way: • Please include a kinamatic diagram (one for velocity and one for acceleration). • Please DO NOT solve this using velocity analysis (cartesian vector analysis). I would like it to be solved using scalar method. We dont use 3D in this course. We only use scalar analysis for the relative velocity equation (writing the x and y components of the equation and solving the equations for the unknowns). I have attached a sample question with solution in order to get an idea on how to use the scalar method to solve my question. I would like question 16-109 to be solved in a similar way. Thank you for your understanding. If you can solve it as soon as possible that would be great and I will give you a thumps up and positive feedback :) 16-109. Member AB has the angular motions shown.
