Transcribed Image Text:

A 16-wheeler Tesla EV long haul truck has a total mass 371onnes and the wheels each weigh 61kg with a radius of gyration of 860mm. The wheel radius is 1250mm. The total resistance to motion is 325N/ton and the engine develops 405kW at a maximum speed of 1950rpm. This power is transmitted through a gear box and differential (rear axle) with a gearing ratio at the axle of 4.66 at an overall total loss of 9%. 1. Determine the tractive resistance in newtons (N). 2. Determine the engine torque (N-m). 3. What is total moment of inertia of the rotating parts (kg-m). 4. Calculate the gearbox ratio (n) in order to maintain an acceleration 0.6m/s on a gradient of 0.5:12.
