QUESTION 1 A portion of a shaft where gear is to be mounted has a diameter of 134 mm. The gear transmits 446 N.mm of torque. The shaft is to be made of SAE 1040 cold-drawn steel. The gear is made from SAE 8650 OQT 1000 steel. The key is made from SAE 1018 steel (Sy: 372 MPa; Su: 441 MPa) The width of the hub of the gear mounted at this location is 10 mm. Compute the Shearing force...
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 6061-T6 aluminum pulley transmits 75 hp at 1,750 rpm. The shaft is 1% inches in diameter and is made from cold-drawn 1040 steel. The key is to be made from cold-drawn 1020 steel. For a safety fac- tor of 3, compute the required square key length for both shear and compression A 6061-T6 aluminum pulley transmits 75 hp at 1,750 rpm. The shaft is 1% inches in diameter and is made from cold-drawn 1040 steel. The key is to...

Q2 (b) The layout of a shaft carrying two pulleys 1 and 2, and supported on two bearings A and B is shown in Figure 2.2. The shaft transmits 7.5 kW power at 360 rpm from pulley 1 to pulley 2. The diameters of pulley 1 and 2 are 250 mm and 500 mm respectively. The masses of pulley 1 and 2 are 10 kg and 30 kg respectively. The belt tensions act vertically downward and ratio of the belt...
A UNS G1030 steel shaft, heat treated to a minimum yield strength of 75 kpsi has a diameter of 1- 7/16 in. The shaft uniformly rotates at 600 rpm and transmits 40 hp through a gear. Find the dimensions of an appropriate key, made from the shaft material, for the gear-shaft attachment. Use a safety factor of 2.8. Your analysis should include failure due to 2 different stress type.
2. Consider the triple speed reduction gear box shown in Figure 1. All the gears are made with a diametral pitch of 16 in. The input of the gear train is gear A, and the output is gear G. The gear train transmits an input toque of 250 lb-in, at a speed of 2,500 rpm clockwise. The number of teeth on each gear is given as follows: NA 24 teeth, Na = 60 teeth, Nc 20 teeth, No 58 teeth,...
