Gearbox and compound train gear system are widely used in power transmission systems to change input torques and rotational speed. Your task in a company that manufactures compound gear system box is to determine the necessary parameters to obtain a required output and securely mounting the gearbox. If the compound gearbox shown in Figure.5 has the following design specifications: B D F LOUTPUT INPUT E T2 Figure.5: Compound gear train system (left), Gearbox securely mounted by clamps (Right)

Q3. Audi’s design of their R8 model is designed in order to have the engine in the rear of the car with the following schematic of their mechanical power transmission. The engine is connected to the gearbox, where gear change occurs and then a driveshaft is used to transfer an equal ratio of power balancing the rear and front wheel power output thus referring to it as an all-wheel drive. The vehicle has been modified by a customer thus resulted to no power transfer to the front wheels although the rear wheels still have the same power output. Using your knowledge, DEFINE and JUSTIFY the possible reasons of why the front drive isn’t functioning. What are the solutions to this fault?
