(3) Non-Planar Free Body Diagrams For each of the following figures (points are per figure): 1. (2) Record any assumptions. 2. (10) Draw a free-body diagram of the system (which is underlined). 3. (3) State how many unique unknown loads are in the diagram (and list these unknowns). A lightweight aluminum bar is attached to a wall at A, and loaded at B and D as shown. Compute the moment of W about A. Gravity acts towards the bottom of the page. (b) (10) In this case, also compute the moment of F about A and express it as a vector, knowing that F has a magnitude of 200 kg. The winch assembly is holding a 100-kg packet in equilibrium, as shown. The Bearing at B is a journal bearing (that is part of a multi-bearing system) and the Bearing at A is a thrust bearing (that is part of a multi-bearing system). Hint: Refer to Table 4.2 for loads associated with nonplanar supports.
