2. The driving and the driven pulley in an open-flat-belt transmission have a diameter of 160 mm each. Calculate the pre-load needed in the belt if a power of 7 kW should be transmitted at 1000 rpm by using only half the wrap angle on each pulley. The coefficient of friction is 0.25, the density of the belt material is 1500 kg /m², and the allowable belt pre-load stress is 5 MPa. Also calculate the cross-sectional area of the belt.
