Vehicle dynamics and handling test question and answers | semester end question and answers |

 Question paper:

1. Explicate the ‘µ’circle diagram or ‘gg’ diagram specifying the physical limitations from vehicle                  dynamics point of view.

2.The data of static weight on each of the tire of a passenger car and lateral weight transfer during                 cornering is shown in Table 1. For the given data, illustrate the forces acting on a vehicle during                 cornering by showing the weight on each tire.

3.Explain the following terms as applied to vehicle dynamics with neat sketches. 

  i. Pitch 

 ii. Slip angle

4. Discuss the significance of understeer gradient with the help of governing equation.

5.A car has a weight of 14000 N and wheelbase of 2.6 m. The % of weight distribution towards front and the rear of the centre of gravity is 58:42. 

  a) Determine the aft and fore position of the centre of gravity for the vehicle. 

  b) Determine the understeer gradient and characteristic speed/critical speed for the vehicle if the                 cornering stiffness of each of the front tires is 650 N/deg and cornering stiffness of each of the rear         tires is 620 N/deg.
