A beam with the cross section shown in the figure carries a bending moment that causes the elastic region to extend 1.5 in. from the neutral axis. Determine the residual stress distribution after the bending moment has been removed. Use σyp = 40 ksi.
modified brayton cycle is to be analyzed using the air-standard assumption with constant specific heats at a
A PM DC motor is rigidly coupled to a fan; the fan load torque is described by the expression TL = 5 + 0.05ω + 0.001ω2, where torque is in Newton-meters and speed in radians per second. The motor has kaφ = kT φ = 2.42; Ra = 0.2 Q, and the inductance ..
