Question

<p>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 38 N. The second force has a magnitude of 58 N and is directed at an angle <em>&#952;</em> with respect to the rod. If the sum of the torques due to the two forces is zero, what must be the angle <em>&#952;</em>?<br /><br /></p>

Explanation / Answer

torque due to first force = 38*d

torque to second force = 58*d*Sin

since net torque =0

38*d= 58*d*Sin

=> = 40.93 degrees with respect to rod
