A mechanic uses a jack to lift up a car. He exerts a force of 11,000 N at a distance of 3m from the axis of rotation. How much torque was put on the car?

Explanation:

Formula for calculating torque is expressed as T = rFsin where;

r is the radius of the  of the arm of the jack = 3m

F is the force exerted = 11000

is the angle of rotation = 90°

On substituting;

a cold ice-tea.

pour in room temperature or cold water. cover the pitcher and refrigerate. steep white or green tea for 6 to 8 hours; steep black or oolong tea for 8 to 12 hours.jun 28, 2015
