2. Power is transmitted to a shaft, supported on bearings 36 inches apart, by a belt running on an 18 inch pulley which overhangs the right bearing by 10 inches. Power is transmitted from the shaft by a belt running on a 10 inch pulley located midway between the bearings. The belt drives are at right angles to each other and the belt tensions are 3 to 1 with the total pull on the tight side of either belt being limited to 600 pounds. (a) Draw the moment diagrams. (b) Determine the necessary size of SAE 1045 transmission shafting (ultimate tensile strength 97,000 psi, tensile elastic limit 58,000 psi). Assume K,= 1.5 and K= 1.0. (c) Calculate the torsional deflection in degrees.

A hydraulic clutch of a motor car works as follows: A foot pedal with a mechanical advantage of 2,5:1 acts on the master cylinder which is 15 mm in diameter. Hydraulic fluid is displaced to the slave cylinder which is 20 mm in diameter. The force from the slave cylinder on the clutch is 850 N and the foot pedal moves 70 mm when pressed in.1.1 Determine the force which must be applied to the foot pedal.1.2 Determine the distance that the slave cylinder will move if the foot is depressed fully.
In the geared shaft shown below, gears A and B and gears C and D are separated by 500 mm. Gears B and C are separated by 400 mm. Gear A is experiencing a 250N⋅m250N⋅m clockwise torque; gear B is experiencing a 75N⋅m75N⋅m counter-clockwise torque; gear C is experiencing a 325N⋅m325N⋅m counter-clockwise torque; and gear D is experiencing a 150N⋅m150N⋅m clockwise torque. What is the absolute maximum shear stress in the shaft (in MPa) if the shaft has a 50-mm diameter?
12. A shaft is supported in two bearings 8 ft. apart and projects 2 ft. beyond the bearings at each end. The shaft carries three pulleys, one at each end and one at the middle of its length. The end pulleys weigh 180 lb. and 100 lb. and their centres of gravity are at 0-15 and 0-20 in. respectively from the shaft axis. The centre pulley weighs 140 lb. and its centre of gravity is 0-25 in. from the shaft axis. If the pulleys are arranged so as to give static balance, determine the dynamic forces produced on the bearings when the shaft rotates at 300 r.p.m.
