Two members, each consisting of straight and 168-mm radius quarter-circle, are connected as shown and support a 500-N load at D. Draw the FBD of the entire frame and members ABC and DBC, including dimensions. Determine the forces in member ABC. Also, calculate the force exerted by member DBC on pin C. 168 mm 168 mm A.

The figure shows a roof truss and the detail of the connection at joint B. Members BC and BE are angle sections with the thickness shown in the figure. The working stresses are 70MPa for shear in the rivets and 140MPa for bearing stress due to the rivets. How many 22mm diameter rivets are required to fasten the following members to the gusset plate: (a) BC; and (b) BE? 000 4 m B с 96 kN D 6 m E 200 KN 4 m F G 4 m 96 kN H to- PBC - -14-mm-thick gusset plate -13-mm-thick angle 6-mm-thick angle PBE

Problem 2: Determine the force in ALL the members of the truss. State if the members are in tension or compression. Show all your work to receive full credit.
