A toggle clamp is used to apply a friction pad to a flywheel mounted at O, as illustrated below. The coefficient of static friction between the friction pad at A and the flywheel is 0.4. The radius of the flywheel is 6 in. For a torque of M = 28 in-lbs applied to the flywheel, determine the force F that must be applied to the handle of the toggle clamp to prevent the flywheel from rotating. Also, determine the internal loads, which include the normal force, N, the shear force, V, and the bending moment, M, at location G of the toggle clamp arm and at location H of the toggle clamp handle. For the online quiz, submit your answer for the shear force, V, at location G of the toggle clamp arm. 2.75 in, -10 in- 4 in 6 in H M A 4 in G 1.2 in 1.2 in 30° F 30° 12 in E

The coeffient of static friction between the uniform bar AB of weight W and the ground is 0.45. Find the smallest angle and the corresponding force P that would initiate simultaneous tipping and sliding of the bar.

The cone clutch transmits the torque C through a conical friction surface with cone angle . The inner and outer radii of the friction surface are a and b, respectively. The left half of the clutch is keyed to the shaft, and the right half drives a machine (not shown) through a gear attached to its outer rim. Assuming uniform pressure on the friction surface, show that the maximum torque that can be transmitted by the clutch is

The force P applied to the brake handle enables the band brake to reduce the angular speed of a rotating drum. If the tensile strength of the band is 3800 lb, find the maximum safe value of P and the corresponding braking torque acting on the drum. Assume that the drum is rotating clockwise.
