A Solid steel shaft running at 600rpm is supported on bearings 600mm apart. The shaft receives 40kW through a 400mm diameter pulley weighing 400N located 300mm to the right of left bearing by a vertical flat belt drive. The power is transmitted from the shaft through another pulley of diameter 600mm weighing 600N located 200mm to the right of right bearing. The belt drives are at right angles to each other and ratio of belt tensions is 3. Determine the size of the shaft necessary, if the allowable shear stress in the shaft material is 40MPa and the loads are steady.

A Hollow power transmission shaft of length ‘L’ 1103 mm, outer diameter ‘D’ 73mm and inner diameter 'd' 50. is required to transmit a power of P 60kW at a speed of 2950rpm. The modulus of rigidity of hardened carbon steel, which the shaft is made of, is 79.5 GPa Calculate the angle of twist of the above stating your answer in degrees?

A maximum torque of 6.75 kNm can be supplied to the constant diameter steel (G= 80 GPa) line shaft by a motor as shown in Figure Q2. At the current normal operation condition, three machines are driven by gear B, C and D on the shaft and they require torques of 3.x kNm, 1.5y kNm and 1.0z kNm, respectively. Parameter x, y, and z are given by: Q2 X=0 Y=0 Z=2 Considering the maximum torque can be supplied by motor, determine the minimum diameter required if the maximum shearing stress in the shaft is limited to 100 MPa. Round your answer to the nearest whole number. (a) -Bearing D Figure Q2

A solid shaft made from AISI 1040 cold-drawn steel is used to carry two V-belt, as shown in the Fig. 3. Pulley A receives power from a motor through a belt, with the belt tensions shown in Fig. 3. The power is transmitted through the shaft and delivered to the belt through pulley B. Assume the belt tension on the loose side is 10 percent of the tension on the tight side.

The disc clutch of an automobile is carried on a 2-inch 6-splined shaft and not to slide under load. The nominal dimensions are as follows: b = 0.25 D; t = 0.075 D and d = 0.85 D. The hub length of 150 % of shaft diameter. Determine the total horsepower transmitted at 3,600 rpm, if the yield strength of the shaft is 1,400 psi

1. A 10 hp. 1400 rpm motor uses a roller chain to drive a line-shaft at 400 rpm with a center to center distance of 2 ft. The motor shaft has a diameter of 1 % inches and the load applied is moderate shock. Determine the approximate length of the chain.
