Chapter 27, Problem 25P

Derive the set of differential equations for a three mass–four spring system (Fig. P27.25) that describes their time motion. Write the three differential equations in matrix form,

[ Acceleration vector ] + [ k / m  matrix ] [ displacement vector  x ] = 0

Note each equation has been divided by the mass. Solve for the eigenvalues and natural frequencies for the following values of mass and spring constants: k 1 = k 4 = 15  N/m,  k 2 = k 3 = 35  N/m, and  m 1 = m 2 = m 3 = 1 .5kg .

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.

4. Steam flows steadily through a turbine at a rate of 47,000 lbm/h, entering at 1000 psia and 800°F and leaving at 6 psia as saturated vapor. If the power generated by the turbine is 3.7 MW, determine the rate of heat loss from the steam.
