Question

The driver of a car is making a right turn. She is applying a force of 10 N to the steering wheel at points A and B as shown below. The forces have parallel lines-of-action, but are opposite in direction.

a. Calculate the resultant moment created by these two forces about point O (center of the wheel). Express this moment as a Cartesian vector.

b. Calculate the resultant moment created by these two forces about point B. Express this moment as a Cartesian vector.

Explanation / Answer

Mo = -10 cos30 (375/2) -10 cos30 (375/2) = -1623.8 N.mm = 1623.8 N.mm (clockwise).

MB = -10 cos30 (375) = -1623.8 N.mm = 1623.8 N.mm (clockwise).
