1. Compute the moment of the 0.4-lb force about the pivot O of the wall-switch toggle.
2. Determine the angle θ which will maximize the Moment MO of the 50-lb force about the shaft axis at O. Also compute MO.
collar c moves along a circular guide with radius R=2ft with a constant speed v=18ft/s. at the instant, the bars AB and BC are vertical and horizontal respectively. Letting L=4ft and H=5ft, determine the angular acceleration of the bars AB and BC ..
Find the differential equation governing the motion of the diver while she is in contact with the board. Neglect any rotational inertia and what is the peak de?ection of the diving board?
Determine the failure load for the crack-free jaw. For the crack-free jaw, what would be the factor of safety based on stress/load. Which failure occurs first- the crack or the failure in the pins
A piston/cylinder has nitrogen gas at 750 K and 1500 kPa. Now it is expanded in a polytropic process with n = 1.2 to P = 750 kPa. Find the final temperature, the specific work and specific heat transfer in the process.
For an adiabatic in viscid flow, write the entropy equation in general coordinate-independent form and in Cartesian coordinates. What does the equation express? Can we say that entropy is constant in an entire such flow (explain your answer)?
Horsepower and efficiency of three-phase motor, If a fully loaded 440V, three-phase motor draws 12.4 A at 86% power factor (pf). It's speed is 1730 rpm and its torque output to a mechanical load is 29.1 lb-ft x 1.356 = 39.5 Nm.
