1. For a publicity stunt to promote a popular children’s TV show, an entertainment company’s engineers must design a static hoist to suspend Bernard the Boisterous Elephant 20-ft in the air. Determine the tension that cables AO, BO, and CO must be able to withstand to keep 250-lb Bernard from falling down onto his adoring crowd.

5. Determine the smallest lever force each, find the applied load P needed to prevent the wheel from rotating if it is subjected to a torque M = 500 Nm. The coefficient of static friction between the belt and the wheel is µs = 0.4. The wheel is pin-connected at its center, B.

8. Given that Ixy = the smooth support at A and the reactions at the pin at B. Water has density of 1.0 Mg/m3. -12.96 X 106 mm4 determine the principal moments of inertia of the shaded area with respect to the centroidal x-y axes. Also specify the angle from the x-axis to the maximum principal moment of inertia.
