A flat belt is required to transmit 35 kw from a pulley of 1.5 m effective diameter running at 300 rpm. The angle of contact spread over 11/24 of the circumference and the coefficient of friction between pulley and belt 0.3. Determine width of belt required. It is given that the belt thickness is 10mm, density of its material is 1.1Mg/m and the related permissible working stress is 2.5 Mpa.
