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…

A smooth sphere of weight Wis supported by a string fastened to a point C on sphere and point A on the smooth vertical wall. The sphere is in contact with the wall at point B as shown in figure. If the length of the string AC is equal to the radius of sphere, then sum of magnitude of tension (T) in the string and reaction (R) on the wall is. W. (Round off two decimal places). A B Wall String Sphere Length of string AC = Radius

Beam AC is in equilibrium with loading 100 N at B shown in the figure when β = 45. Determine the unknown forces Ax and Ay at A in x and y direction and Rc perpendicular to the beam AC in y’ direction at C by using the equilibrium equations: ∑ ???= 0 ; ∑ ??y= 0; and ∑ ???= 0 where o is an arbitrary point. (you have three equations to solve three unknowns)
