Question 1 [15 Marks] An open flat belt is to transmit 10 kW. Assume a factor of safety of eight (8) and ultimate tensile stress for the flat belt material of 20 MPa. Assume u = 0.35. The small pulley 170 mm The small pulley rotates at 800 r/min large pulley rotates at approximately 260 r/min Both pulleys have a width of 100 mm Center distance between the pulleys is 800 mm 1.1 Specify a belt, i.e. the width, thickness, length, and grade (13) 1.2 Calculate a suitable initial tension.
