Sample Question 1: Suppose the length of a wrench is 0.2 meters and the applied force is 100 N.
If the force is exerted perpendicular to the wrench, what is the torque? If you apply the force with an
angle, do you think that the torque will be decreased or increased?
Solution: Use the formula, T = Fd. Here, F is given as 100 N, and d is 0.2 meters. So, the
produced torque is 100 x 0.2 = 20 J. If you apply the force with an angle, the torque will be less
than 20 J because the length of the lever arm will be shortened.
