A countershaft, made of AISI 1035 CD steel, carrying two V-belt pulleys is shown in the figure. Pulley A receives power from a motor through a belt with the belt tensions shown. The power is transmitted through the shaft and delivered to the belt on pulley B. Assume the belt tension on the loose side at B is 25 percent of the tension on the tight side (F2 - 0.25 F) 1) Based on the equations for yielding conditions discussed...

Q2. Figure Q2 shows a shaft which transmits a power of 48 kW through flat belts. Pulley A is driven by a motor which rotates at 3000 rpm. The diameter of pulley A is 400 mm and that of pulley B is 250 mm. The thickness of the belts is 4 mm and they are made of a material with density of 1100 kg/m3. Assume no sliding between pulleys and belts a) Calculate the speed of the belt and the...
A countershaft in a machine has two pulleys mounted on it for power transmission and is supported by cylindrical roller bearings at the ends
A countershaft in a machine has two pulleys mounted on it for power transmission and is supported by cylindrical roller bearings at the ends. The countershaft runs at 1,500 revolutions per minute. The belt tension on the loose side of Pulley B is 20% of the tension on tight side. Design the shaft, mounting components. The design will include the following items. (1) Shaft material selection based on strength and cost considerations. (Give a comparison b/w at least two possible materials) (2) Shaft...
