To develop the ability to break a frame or machine down into subsystems and to determine the forces developed at internal pin connections. Frames and machines are systems of pin-connected, multiforce members. Frames are designed to support loads, whereas machines are designed to transmit or alter the effects of loads. For a frame or machine to be in equilibrium, each member of the frame or machine system must be in equilibrium. Free-body diagrams of the overall system, as well as individual members, groups of members, and subsystems, must be drawn.

The clamping hooks shown (Figure 1) are used to lift a uniform plate. Complete the free-body diagram of hooked member 8C by adding the forces that act on it. Draw your vectors starting at the appropriate black dots. The location, orientation, and relative length of your vectors will be graded.

b. This question will be shown after you complete previous question (s).

c. This question will be shown after you complete previous question (s).
