Draw the Free-Body Diagram. Provide a direction and a name for each reaction force nd moment. Only the minimum number of required reactions is required. None of the ptional and ambiguous reactions need to be drawn.

For the beams and loading shown below. a) Draw the shear and moment diagrams b) Determine the maximum absolute values of the bending moment You MUST draw the free body diagram and solve for reaction forces and moment, as necessary. You MUST show the equations that the shear and moment diagrams are based on. A P B L P C P a Р b

Find the resultant force from the force reactions found at B in problem 1. (Provide size and direction with the angle to the +x axis.)   (ps. I have already solved question #1. I did not realize there was a "part b" to it)

Learning Goal: To be able to solve three-dimensional equilibrium problems using the equations of equilibrium. Part A As with two-dimensional problems, a free-body diagram is the first step in solving three-dimensional equilibrium problems. For the free-body diagram, it is important to identify the appropriate reaction forces and couple moments that act in three dimensions. At a support, a force arises when translation of the attached member is restricted and a couple moment arises when rotation is prevented.For a rigid body to be in equilibrium when subjected to a force system, both the resultant force and the resultant couple moment acting on the body must be zero. These two conditions are expressed as The J-shaped member shown in the figure(Figure 1) is supported by a cable DE and a single journal bearing with a square shaft at A. Determine the reaction forces Ay and Az at support A required to keep the system in equilibrium. The cylinder has a weight WB = 5.60 lb , and F = 1.50 Ib…

The torsional spring at B is undeformed when bars OB and BD are both in the vertical position and overlap. If a force F is required to position the bars at a steady orientation 0 = 54°, determine the torsional spring stiffness kt. The slot at C is smooth, and the weight of the bars is negligible. In this configuration, the pin at C is positioned at the midpoint of the slotted bar. 62 8 A 682 kT B Answer: KT= i 0.1559 Fb E
