A body with mass of 250 kg is supported by five 15 mm diameter cables. Determine the normal stress in each cables.

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
