A cone clutch is drawn showing the mating surfaces. Assume that the mating parts are forced into contact with a normal pressure on the mating surfaces of 10 psi. The area of contact is the product of the 2 inches dimension and the mean circumference of the mating parts, that is, 2 × π × 8. The total normal force in pounds is 10 times the area just found. If the coefficient of friction is 0.35, determine the force of friction between the mating surfaces. Give solution. (Ans. F=176 lb)

A 150 lb man stands on a 60 lb bar to which the cable is tied at B. The cable passes over two fixed pegs with coefficient of frictions as indicated. You may treat the cable the same as you would treat a flexible flat belt. assume the normal force exerted by the man in the bar acts downward through point A. Find the smallest force the man can exert on the cable if the bar is to remain horizontal.

A block of mass m = 3.1 kg is placed on a rough incline surface making an angle 0 = 27.7. with horizontal. A force F parallel to the ground is applied to the block. Due to the applied force the block moved x = 0.53 meter along the inclined surface with constant speed. If the inclined surface has kinetic friction coefficient uk = 0.23 what is the work done by the friction force? Provide your answer with 2 decimal places. Take g = 9.81 m/s2 HK
