Question

A rod is lying on the top of a table. One end of the rod is hinged to the table so that the rod can rotate freely on the table top. Two forces, both parallel to the table top, act on the rod at the same place. One force is directed perpendicular to the rod and has a magnitude of 39 N. The second force has a magnitude of 61 N and is directed at an angle θ with respect to the rod. If the sum of the torques due to the two forces is zero, what must be the angle θ?

          A rod is lying on the top of a table. One end of the rod is
hinged to the table so that the rod can rotate freely on the table
top. Two forces, both parallel to the table top, act on the rod at
the same place. One force is directed perpendicular to the rod and
has a magnitude of 39 N. The second force has a magnitude of 61 N
and is directed at an angle θ with respect to
the rod. If the sum of the torques due to the two forces is zero,
what must be the angle θ?

Step 1

Step 1: The torque due to the force perpendicular to the rod (39 N) is given by \(39 \times D\), where D is the distance from the hinge point. Show more…
