Problem 6: For the two systems shown below, separately, identify the degrees of freedom and then write the equations of motion, respectively. Also, for each system, determine the natural frequency and damping ratio. The two systems shown are set into motion via initial condition. For the first figure of problem 6 (the circular disc), the disc is performing fixed axis rotation about its center of mass, G. It has a radius of gyration kG about the axis through the center...

Problem 4 The pumping system shown in the figure below to deliver 3 cfs of 60°F water. The total elevation difference between is 84 ft. The suction line is a 6-inch diameter, 300-ft long cast-iron pipe. The discharge line is 6-inch diameter in an 860-ft long plastic pipe. The suction inlet for the pump is 20 ft above the reservoir. The atmospheric pressure is 14.70 psia. The required NPSH is 7.0 ft. Minor losses include entrance: k, = 0.5, open...
For each system listed in the first column of the table below, decide (if possible) whether the change described in the second column will increase the entropy S of the system, decrease S, or leave S unchanged. If you don't have enough information to decide, check the "not enough information" button in the last column. System Change AS O AS < 0 O AS = 0 | A few moles of helium (He) gas. The helium is cooled from 40.0...
