Q.1) Draw a Free Body Diagram for each object indicated below. Include values for known forces and moments and variables for any unknown quantity. Use dashed lines to include any dimensions or angles when appropriate. Any two-force member should be modeled using a single force in the appropriate direction. (a) Draw member ABD assuming all members have negligible mass. B, C, and D are all pin connections. in. A 50 lb 2 in. 5 in. 3 in. (b) Draw member ABC. Assume the mass of ABC is negligible, the mass and size of pulleys C and D are negligible and the pulleys are frictionless. A represents a pin connection. 0.5 m 0.4m 0.4 m 60 kg A 400 kg uniform steel beam is welded to the wall at 4. An 80 kg man stands on the beam while holding the end of a cable that wraps around a pulley having negligible friction and negligible mass. Treat the man as a rigid body with two feet contacting the beam. (c) Draw the steel beam and man as one FBD. (d) Draw the man as a separate FBD.
