a) Figure Q4 shows a Stage 1 to Stage 2 compound gear train comprising of Gears A, B, C and D. The number of teeth for each gear are: N₁= 16, N₂ = 42, Nc = 26 and ND = 56. If the input shaft rotates at 2750 revolutions per minute (rpm), calculate the angular velocity (w) in rad/s for each gear in the compound gear train. Give your answer in rad/s to two decimal places. Gear B- Gear A- Input shaft- Stage 1- Gear C- -Stage 2 -Intermediate shaft Figure Q4 -Gear D -Output shaft b) If a motor with a power rating of 1200 Watt is coupled to the input shaft at Gear A in Figure Q4 and running at 2750 revolutions per minute (rpm), calculate the torque (Nm) at the input shaft, intermediate shaft and the output shaft. Assume no losses and 100% efficiency. c) Draw a typical indicator diagram of pressure versus volume (p-v) to illustrate the cycle of a four stroke reciprocating internal combustion [RIC] engine. Clearly label each part of the p-v indicator diagram and indicate when the piston is at top dead centre and bottom dead centre.
