Question (1)
A flat belt drive is required for a piston pump. The pump is driven by a 40-kW electric motor
running at 1300 rpm with a pulley of 230 mm diameter. The pump pulley is 600 mm in diameter.
The friction coefficient is 0.75, the density of the belt is 1150 kg/m$^3$ and the maximum
permissible stress is 7 MPa. The distance between pulley centers is 1.4 m. The belt thickness is
3.2 mm. Determine the required belt width.
