Assume a rod made of a steel with a maximum allowable stress oa = 155 MPa. Can the rod safely support the load to which it will be subjected? The magnitude of the force FBC in the rod was 50 kN and its diameter is 20 mm. If not. redesign the rod

The center post B of the assembly has an original length of 124.7 mm, whereas posts A and C have a length of 125 mm. If the caps on the top and bottom can be considered rigid, determine the average normal stress in each post. The posts are made of aluminum and have a cross-sectional area of 400 mm Eal = 70 GPa. |800 kN/m +100 mm -100 mm A B 125 mm I800 kN/m Answer: 0A = 0c = 189 MPa, oB 21.4 MPа

A steel [E = 200 GPa] bar (1) supports beam AB. The cross-sectional area of the bar is 540 mm?. If the stress in the bar must not exceed 450 MPa and the maximum deformation in the bar must not exceed 20 mm, determine the maximum load P that may be supported by this structure. Use dimensions of a = 4 m, b = 2.4 m, and c = 5.2 m. (1) B' A a Answer: P = i kN
