The figure shows a workshop belt sander driven by an electric motor through a gearbox with a 3 : 1 reduction ratio, i.e., the motor turns 3 times for each turn of the drive wheel a. The radii of the wheels in the diagram are: r = 32 cm, r = r = 14 cm. a. It is desired to have the belt achieve a working speed of 5.0 m/s within 26 seconds. If the motor accelerates with constant acceleration from stationary, determine the desired acceleration of the belt, abelt and hence the required angular acceleration of the motor, ameer Abelt = m/s2 Omotor = rad/s2 Give your answer to 4 significant figures. (2 marks) b. If the motor and belt have an effective moment of inertia of 0.13 kg m2 (as seen at the motor output) determine the torque of the motor, To required to achieve the acceleration identified in part (a). T = Nm. Give your answer to 4 significant figures. (1 mark) C. A point P exists on pulley as shown in the diagram. When the belt is moving at 2.5 m/s and accelerating at the figure you calculated in part (a), determine the normal and tangential acceleration of point P. Poormal m/s2 Pangential = m/s? Give your answer to 4 significant figures. (1 mark) Direction of Belt olo Figure: Floor Standing Belt Sander
