Question
2. A horizontal rod that is pinned at one end is lying on a horizontal frictionless surface. The mass of the rod is 3.78kg and it has an overall length of 0.88m. Two horizontal forces act on the rod in opposite directions, both perpendicular to the rod itself. The first is applied at a point that is 0.35m from the pinned end and has a magnitude of 28.7N. The second is applied at a point that is 0.68m from the pinned end of the rod and has a magnitude of 22.1N. Draw a sketch of the situation as seen from above, being sure to indicate the direction of the x-, y-, and Z-axes. What is the rotational acceleration of the rod due to these two forces? Use your sketch to correctly indicate the direction of this rotational acceleration in terms of a unit vector.
