Problem The truss is made from three pin-connected members. Determine the maximum average normal stress developed in each member when the truss is subjected to the load shown. All members have a width of 5 cm and a thickness of 2 cm. All pins have a diameter of 2.5 cm. Follow these steps in answering this problem: 1. Draw the FBD of the whole structure. Solve for reactions A and C. 2. 3. Consider pin B and solve FAB and FBC. 4. Consider pin C (or pin A) and solve FAC. 5. Draw the section needed to solve the maximum 4 m 3 m 1000 N B average normal stress, noting if the member is under Figure adapted from Hibbeler's Mechanics of tension or compression, then solve the internal forces. Materials. 6. Solve for the stresses. Point to ponder: If all members are made of the same material, which material will fail first as the load is continually increased?
