HW8
A shaft fitted with a flywheel rotates at 650 r.p.m. and drives a machine. The
torque of machine varies in a cyclic manner over a period of 2 revolutions. The
torque rises from 650 N-m to 2200 N-m uniformly during 110° and remains
constant for the following 270°. It then falls uniformly to 600 N-m during the next
100° and remains constant for the end cycle, the cycle being repeated thereafter.
Determine the power required to drive the machine and percentage fluctuation in
speed, if the driving torque applied to the shaft is constant and the mass of the
flywheel is 180 kg with radius of gyration of 35 cm.

- Assume multiple single degree of freedom systems with natural periods T ∈ [0.05, 2.00] seconds with in-crement of period dT = 0.05 seconds. Assume three cases of damping ratio: Case (A) ξ = 0%; Case (B)ξ = 2%; Case (C) ξ = 5%. The systems are initially at rest. Thus, the initial conditions are u(t = 0) = 0 anḋu(t = 0) = 0. The systems are subjected to the base acceleration that was provided in the ElCentro.txt file(i.e., first column). For the systems in Case (A), Case (B), and Case (C) and for each natural period computethe peak acceleration, peak velocity, and peak displacement responses to the given base excitation. Please,use the Newmark method for β = 1/4 (average acceleration) to compute the responses. Create threeplots with three lines in each plot.
