SkyWest interview Questions and Answers 100% correct Describe Mach Tuck -Result of an aft ward shift in the center of lift causing a nose down pitching moment due to two reasons. 1) Shockwave induced flow separation, which normally begins near the wing root, causes a decrease in the downwash velocity over the elevator and produces a tendency for the aircraft to nose down 2) Aft ward movement of the center of lift, which tends to unbalance the equilibrium of the plane in relation to its CG in...

This is an old second midterm for the course, MATH 246, from the semester of Fall 2016. The exam covers; mass spring dampener systems, damping coefficients, time domain plots, general solution, particular solution, characteristic polynomials, chracteristic equations, homogenous equation, method of underdetermined coefficients, key identities, specific solution, varaiation of parameters, and Laplace transformation.

This is a midterm study guide that was made from notes taken during a review session for the first midterm. It covers every equation needed for the midterm and the concepts that the first midterm would tackle. Concepts include; SDOF systems, Springs laws, Pendulums, Force Balance method, and Base excitation(single base)
