For the gear train shown below determine the velocity ratio, output speed, output direction, output torque, output power and holding torque if the gear A is at clockwise direction

A gear box has an input speed of 1800 rev/min clockwise and an output speed of 400 rev/min The input power is 25kW and the efficiency is 90%. Compute the input torque                                                                                                                                                  the output power                                                                                                                                                       3. the output torque

4. What is the overall gear ratio for the following compound gear train? What is the output shaft speed and direction if the input shaft rotates clockwise at 1000 rpm? 8 teeth, Ø 5mm 16 teeth, Ø 10mm 24 teeth, Ø 15mm 32 teeth, Ø 20mm driver driven

Pls explain to step by step and  i will rate your answer immediately. Thanks
