Q1 Two spur gears in a simple train shown in Figure Q1 are having the same module, m=2 and their respective number of teeth is Nin = 30 for the driver gear, and Nra = 45 for the driven gear. The inertia of the gear attached to the motor is l. = 0.0kgm and the inertia of the second gear is lo=0_7kgm?. The second gear is connected to a pulley with the radius of 30 mm. The pulley is hoisting up the 2kg load with acceleration of a = 2 ms. Given the gear transmission efficiency is 90%. Based on the module and number of teeth given, examine the pitch diameter of each gear. (4 marks) (b) Considering acceleration of load at 2 ms? evaluate the torque of the motor to overcome gears inertia. (9 marks) (c) Considering the 2 kg load, examine the torque required to accelerate the load through gear system. (9 marks) Suggest the minimum torque of the motor to accelerate the 2 kg load at 2 ms. (3 marks) (d)
