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
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 tensions on tight side to slack side for each pulley is 2.5:1. The shaft is made of plain carbon steel having Syı = 380 MPa and the factor of safety is 3.0. Determine the diameter of the shaft.

A transmission shaft is supported on two bearings which are 1m apart. Power is supplied to the shaft by means of a flexible coupling, which is located to the left of left hand bearing. Power is transmitted from the shaft by means of a belt pulley, 250 mm
A transmission shaft is supported on two bearings which are 1m apart. Power is supplied to the shaft by means of a flexible coupling, which is located to the left of left hand bearing. Power is transmitted from the shaft by means of a belt pulley, 250 mm diameter, which is located at a distance of 300 mm from the left hand bearing. The mass of the pulley is 20 kg and the ratio of belt tension on tight and slack sides is 2:1. The...
A line shaft supporting two pulleys A and B is shown in Figure (below).
QUESTION 2 A line shaft supporting two pulleys A and B is shown in Figure (below). Power is supplied to the shaft by means of a vertical belt on pulley A, which is then transmitted to pulley B carrying a horizontal belt. The ratio of belt tensions on tight and loose sides is 3:1 and the maximum tension in either belt is limited to 2.7 kN. The maximum belts tension will occur in belt on pulley A due to smaller diameter....
