The T-bar AEBF is connected to rod CD, with the joint at F being equivalent to a slider bearing. The supports at A and C are slider bearings, and thrust bearings are found at B and D. The two applied forces, which act at the midpoint of the arm EF, are parallel to the y- and z-axes, respectively. Neglecting the weights of the members, draw the FBDs for the entire structure, the T-bar, and rod CD. Determine the total number of unknowns.
1) Use the method of Joints to calculate the force in each member of the loaded truss illustrated and state weather each member is in tension or compression. Also calculate the reaction forces at a and e.
The frame shown is loaded by a 180-1b force
applied to member AE. Determine the force at pin
A, the reaction at support B, and the contact force
at roller C. Note that there is no friction at rollers C
and D.
