Chapter 5, Problem 13SP
A wrench is 50.0 cm long. It is placed on a nut, and a force of 100 N is applied perpendicular to the wrench handle. This force is in the plane of the wrench and nut, at a distance of 30.0 cm from the center of the nut. Determine the size of the torque twisting the nut. [Hint: Draw a diagram and label the moment arm. Watch out for units.]

A mechanic loosening a nut and found that the nut needs a torque with a magnitude of 46 N · m. If the mechanic grasps the wrench as shown in the figure below. The distance between his hand and the center of nut r = 0.33 m and the angle between his hand and the wrench is θθ = 50 degrees. Determine the magnitude of the force F (in newtons) she must exert on the wrench.
As a torque activity, your Physics TA sets up the arrangement shown below.
A uniform rod of mass mr = 143 g and length L = 100.0 cm is attached to the wall with a pin as shown. Cords are attached to the rod at the r1 = 10.0 cm and r2 = 90.0 cm mark, passed over pulleys, and masses of m1 = 286 g and m2 = 177 g are attached. Your TA asks you to determine the following.
(a) The position r3 on the rod where you would suspend a mass
m3 = 200 g
in order to balance the rod and keep it horizontal if released from a horizontal position. In addition, for this case, what force (magnitude and direction) does the pin exert on the rod? Use standard angle notation to determine the direction of the force the pin exerts on the rod. Express the direction of the force the pin exerts on the rod as the angle ?F, measured with respect to the positive x-axis (counterclockwise is positive and clockwise is negative).
