The rigid bar ABC is supported by a pin at point A and by two wires attached at B and C as shown in the figure. If the applied point load P produces a clockwise rotation of the rigid bar ABC of 5°, find the normal strain for both wires. All dimensions in mm.
The three-bar truss ABC shown in the figure has a span L = 3 m and is constructed of steel pipes having cross-sectional area A = 3900 mm and modulus of elasticity E = 200 GPa. A load P acts horizontally to the right at joint C. (a) If P= 500 kN, what is the horizontal displacement of joint B?

3.32. One mole of an ideal gas, initially at 30°C and 1 bar, is changed to 130°C and 10 bar by three different mechanically reversible processes: The gas is first heated at constant volume until its temperature is 130°C; then it is compressed isothermally until its pressure is 10 bar The gas is first heated at constant pressure until its temperature is 130°C; then it is compressed isothermally to 10 bar The gas is first compressed isothermally to 10 bar;...
