GATE 2019 Mechanical Engineering Q29

Question

A car having weight W is moving in the direction as shown in the figure. The center of gravity (CG) of the car is located at height h from the ground, midway between the front and rear wheels. The distance between the front and rear wheels is l. The acceleration of the car is a, and acceleration due to gravity is g. The reactions on the front wheels (Rf) and rear wheels (Rr) are given by

Accepted Answer

$R_f = \frac{W}{2} - \frac{W}{g} \left(\frac{h}{l}\right) a; R_r = \frac{W}{2} + \frac{W}{g} \left(\frac{h}{l}\right) a$

Answer

$R_f = R_r = \frac{W}{2} - \frac{W}{g} \left(\frac{h}{l}\right) a$

Answer

$R_f = \frac{W}{2} + \frac{W}{g} \left(\frac{h}{l}\right) a; R_r = \frac{W}{2} - \frac{W}{g} \left(\frac{h}{l}\right) a$

Answer

$R_f = R_r = \frac{W}{2} + \frac{W}{g} \left(\frac{h}{l}\right) a$
