3. The figure shows a frame supported by pins at A and D and carries a triangular load
of maximum intensity 720 N/m. A clockwise couple of magnitude M acts on the
frame at pin D.
(a) Calculate the reaction components at pin A.
(b) Calculate the magnitude of the couple M necessary to keep the frame in equi-
librium.
(c) Calculate the internal forces F and V and the bending moment Mj acting on
cross section J located 0.30 m above the bottom point E.
