Question

A scooter has the following specifications￾Kerb weight = 110 kg Rider weight = 70 kg Front Tire = 90/90-12 Rear Tire = 90/90-12 Coefficient of Rolling Resistance = 0.01 Total Reduction (From motor to wheel) = 9 Maximum motor output power = 5 kW Assuming g=9.8 m/s^2 A. Find the motor speed (in rpm) for a maximum scooter speed of 80 kmph B. Find the minimum motor output torque to achieve 0 to 40 kmph in 3 sec. You can ignore aerodynamic resistance. Assume that the motor torque and power graph is as follows. Note : Assumptions are allowed as far as they donât conflict with the data given.
