Consider the bar/roller assembly shown in the figure below. The roller and surface at point A are frictionless. Two loads are applied to the bar: a couple-moment and a force, as indicated in the figure. 1. Draw a FBD which is suitable for solution of this problem, when seeking to find the reactions at the supports, Points A and B. You must draw a separate diagram and you may NOT use the existing figure given here. In your FBD, it is essential that you make clear precisely what object or collection of objects actually defines your “free body". Your FBD must clearly/correctly show all reactions at the supports, Points A and B, in addition to the applied load(s). You may neglect the weight of the assembly in this problem. The FBD should define the positive “x" and “y" directions, and include the dimensions necessary for computing moments. 2. Write the equilibrium equations and solve for the reactions at the supports (the roller, Point A and the pin, Point B). You must be clear in your results with respect to the direction in which the reactions act on the body. Express results in units consistent with that of the given figure.
