Learning Goal: To understand how to construct a free-body diagram for an object that can be treated as a particle. The free-body diagram is a fundamental tool used in engineering mechanics. It is simply a sketch that shows the particle "free" from its surroundings with all forces that act on the particle. By correctly constructing a free-body diagram, one can account for all of the forces in the equations of equilibrium. It is often helpful to draw an enclosing circle (or loop) around the object(s) of interest and account for (a) forces in cables cut by the circle, (b) reaction forces between the object and any supports at the boundary of the circle, and (c) the weight of the obiect/s) enclosed by the circle As shown, a light hangs from a chain that is connected to a ring held in place by two ropes. One rope is attached directly to a tie-down on a wall, and the other rope passes over a pulley that is mounted on the ceiling before being attached to a tie-down on the opposite wall. (Figure 2) Complete the free-body diagram of the light by drawing the forces that act on it. Draw the weight force vector starting at point D. Draw the tension force vectors starting at the point of contact between the chain and the light [i.e. the black dot above the point D]. The orientation of the vectors will be graded. The exact length of the vectors will not be graded. ▸ View Available Hint(s) + Σ 血 ?
