Figure Q4 shows a racing car with a mass of 975 kg that was tested for the naximum acceleration it could achieve. The centre of gravity G of the car is 0.55 n above the ground level and the dimensions a and b are 1.82 and 2.20 m espectively. The coefficient of static friction is 0.68. The car is rear wheel driven. ) Draw the free body diagram for the car. ) Draw the kinetic diagram for the car. :) Determine the maximum possible acceleration for the car and comment on the reaction force at the point A. 1) Determine the maximum possible acceleration of the car if the powertrain is changed to a four-wheel driven mode. Assume that both front and rear wheels are about to slip. B Figure Q4

A mechanical drawing is described as a technical drawing created by engineers following standard layout conventions, terminology, interpretation, and many other factors. It is also known as an engineering drawing.
