CALCULATIONS MUST BE SHOWN THAT SUPPORT THE ANSWER TO RECEIVE CREDIT. 1) Determine the magnitude of the moment of the force about point D. All lengths
are given in inches. \
A(1.-1,6)+\ M = 848.53 lb-in 2) Determine the support reactions for the frame shown. A is a roller and D is a
ﬁxed support. 9 k/ft Ay= 10k (up)
Dy=17k(11p) Md = 24 k—ﬁ (cow) 5-0" 3) Draw the shear and bending moment diagrams for the loading condition below. 12m 3m 3m 3m 9m 4) Determine the force in members GI, GH, and LM and indicate if the member is in
tension or compression. List all zero force members. 8ft 8ft Zero Force Members : FG, JK GH=25k(T)
ML=15k(T) 5) Determine the moment of inertia of the shaded area about the y-axis by
integration. Iy = 307.4 in“ 6) If the weight of C is 400 lb, determine the weight of A to hold the assembly in
equilibrium. W: 2001b ...
