A leather belt 9 mm x 250 mm is used to drive a cast iron pulley 900 mm in diameter at 336 r.p.m. if the active arc on the smaller pulley is 120° and the stress in the tight side is 2MPa.
Find the power capacity of the belt.
The density of leather may be taken as 980 kg/m³, and the coefficient of friction (μ) of leather on cast iron is 0.35.

A-V belt is to transmit 20 kW from a 250 mm pitch diameter sheave to a 900 mm diameter pulley. The center distance between the two shafts is 1000 mm. The groove angle is 40' and the coefficient of friction for the belt and sheave is 0.2 and the coefficient of friction between the belt and flat pulley is 0.2. The cross-section of the belt is 40 mm wide at the top, 20 mm wide at the bottom and 25...

An overhang hollow shaft carries a 900 mm diameter pulley, whose centre is 250 mm from the centre of the nearest bearing. The weight of the pulley is 600 N and the angle of lap is 180°. The pulley is driven by a motor vertically below it. If permissible tension in the belt is 2650 N and if coefficient of friction between the belt and pulley surface is 0.3, estimate, diameters of shaft, when the internal 15. diameter is 0.6...

A cast iron flywheel used for a four stroke I.C. engine is developing 187.5 kW at 250 r.p.m. The hoop stress developed in the flywheel is 5.2 MPa. The total fluctuation of speed is to be limited to 3% of the mean speed. If the work done during the power stroke is 1/3 times more than the average workdone during the whole cycle, find: 1. mean diameter of the flywheel,...

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...

Figure 1 shows the layout of countershaft used to transmit power to a blower through a pulley drive (4-5). Pulley (driving sheave) 4 has a diameter of 125-mm and pulley (driven sheave) 5 has a diameter of 75 mm. Pulley 5 is mounted vertically below pulley 4 (as shown in the figure). Belt tension on the loose side is 20% of the tension on the tight side. A power of 7.5 kW is transmitted via the gear set (2-3) from...
