Question

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?

Answer 1

The amount of torque put on the car is 33,000Nm

Step-by-step explanation:

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

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

F is the force exerted = 11000

`\theta\\` is the angle of rotation = 90°

On substituting;

`T = 3*11000sin90^(o) \\T = 3*11000 (sin90^(o) =1)\\T = 33000Nm`
