A steel rod 3.0 m long has a cross-sectional area of 0.40 cm2. The rod is now hung by one end from a support structure, and a 600 kg weight is hung from the rod’s lower end. Given g = 9.8 ms-2. Calculate the stress of the rod.

A 20 KN weight is suspended by two wires as shown in the figure. The length of each wire is 2 meter. The steel wire (E value 200 GPa) has a cross-sectional area of 60 x 10-6 m² and the aluminum wire (Evalue 70 GPa) has a cross-sectional area of 120 x 10-6 m². The stress in aluminum wire is Aluminum Steel 20 kN

40 cm I 30 cm 50 cm 3. Using the shape shown in the figure, for a design moment of 7500 N.m, what are the maximum stress values at the bottom flange and the top flange? The thickness of each plate composing this shape is 3 cm
