A plumber applies a torque of 408 to a bolt using a wrench. If he moves his hand twice as far away on the wrench's handle from the bolt (doubling the radius), but applies the same force
as before, how much torque will he now apply?

816

Explanation:

We must remember that torque is defined as the product of a force by a distance.

This distance is measured from the pivot point of the Bolt to the point where the force is applied. in this way, we have the following equation to be able to determine the torque.

Now if we double the turning distance we have the torque should also be double.

answer: a) y=-8x+5

a) m= -8

b) m= -2

c) m= 7

d) m= 6
