Problem 006-fr
In the structure shown in Fig. P-006(FR-H), all members are assumed to be solid rigid members. The system is pinned to the wall at point A and supported by a roller at point E. Calculate the force on member BD and the reactions at A and E.
 

Problem 694
The frame shown in Fig. P-694 is of constant cross section and is perfectly restrained at its lower end. Compute the vertical deflection caused by the couple M.
