Question

Review Concept Simulation 9.2 and Conceptual Example 7 as background material for this problem. A jet transport has a weight of 1.36 x 106 N and is at rest on the runway. The two rear wheels are 17.0 m behind the front wheel, and the plane's center of gravity is 12.6 m behind the front wheel. Determine the normal force exerted by the ground on (a) the front wheel and on (b) each of the two rear wheels.

Answer 1

(12.6 4.4m force balance in vertical it aF2 = fg fit af = 1.36 X 100 N torque balance about front wheel ax ( 2 ) = fax 1.36X 108x1206 3817 S IF, = 5:04 X 105 N.
