QUESTIQ? 3 FIGURE 2 The shaft shown in FIGURE 2 is supported by TWO bearings with a centre distance of 950 mm . A 25 kW electric motor rotates at

and drives the shaft by means of a pinion with a pitch circle diameter of 125 mm and a gear ratio of

. The driven gear is keyed to the shaft at 600 mm to the right of the left-hand bearing. A flywheel with a mass of 220 kg is keyed at a distance of 250 mm to the right of the left-hand bearing. A pulley with a diameter of 380 mm is keyed to the right-hand end of the shaft, 250 mm to the right of the right-hand bearing. The tension ratio of the flat belt is

and the drive is vertical, as shown in FIGURE 2. Calculate the following: 3.1 The torque transmitted by the motor to the shaft 3.2 The belt tension

and

3.3 The tangential force between the gear teeth (pressure angle is

) 3.4 The radial force between the gear teeth 3.5 The vertical reactions on the shaft bearings 3.6 The horizontal reactions on the shaft bearings
