a. In a steering wheel assembly, a Hooke's universal joint connects two shafts which are inclined at to each other. If the driving shaft speed is 500 rev/min, determine the maximum and minimum speeds of the driven shaft.
b. Aerodynamic, road load and rolling resistance forces are of particular interest for their effect on fuel consumption. Explain these using appropriate diagrams.
c. Explain FIVE benefits accrued when operating a third differential between front and rear wheel drive axles during the final drive transmission of a vehicle.
