Homework Answers
Please refer the following image for the solution.
Right direction one arrow means anticlockwise rotation(90o) with that respective axis and left direction arrow means clockwise rotation (90o) with that respective axis. Two arrow means two rotation (90o+90o = 180o) and three arrow means three rotation (90o+90o + 90o= 270o). So, in this problem, one arrow in left direction means we need to rotate the object along X-axis in clockwise for 90o.

The figure above shows an H-like object that is free to rotate (in the plane of the page) about the fixed axis shown. A force is applied at each of the six locations shown, one location at a time. In each case the force is the same size and is always straight right. Rank the locations based on the magnitude of the torque that will result when the force is applied at that location.
