5. A plate clutch consists of a flat driven plate gripped between a driving plate and presser plate so that there are two active driving surfaces, cach having an inner diameter 200 mm and an outer diameter 350 mm. u 0-4. The working pressure is limited to 170 kN/m?. Assuming the pressure is uniform, calculate the power which can be transmitted at 1000 rev/min. If the clutch becomes worn so that the intensity of pressure is inverscly proportional to the radius, the total axial force on the presser plate remaining unaltered, calculate the power which can now be transmitted at 1000 rev/min and the greatest intensity of pressure on the friction surfaces. (U. Lond.) (Answer: 130KW; 127 kW; 234 kN/m²)

Q.1 Explain why torsional coil springs are fitted inside a clutch friction disc. Q.2 Study examples of competition sintered or 'paddle' type clutches. Most of them do not have torsional springs fitted to the friction disc/plate. Suggest why springs are not fitted to these types of clutches.
5. For the engine-transmission-propeller problem shown below, The engine generates a torque of 219lb-ft, and it is bolted to a frame at locations A and B. The transmission reverses the rotation direction. The transmission ratio is 1.5 (i.e. the propeller speed is -1/1.5 the engine speed, the minus sign indicates the change in direction). d. Sketch the free body diagram. Be sure to show the torques at the input and outputs to the different components. Note the change in the rotation direction between the engine and shaft. e.
