A composite bar is constructed from a steel rod of (25 mm) diameter surrounded by a copper tube of (50 mm) outside diameter and (25 mm) inside diameter. The rod and tube are joined by tow (20 mm) diam. pins as shown in figure. Find the shear stress set up in the pins if, after pinning, the temperature is raised by 50°C. For steel E= 210 GN/m2 and a 11*10 per "C, for copper E= 10' GN/m and a = 17*10“ per °C.

A solid steel bar 250 mm long is 10 mm square over part of its length, the remainder being circular with a diameter of 25 mm. A gradually applied tensile load P kN induces maximum stress in the bar of 200 MPa. The total strain energy in the bar when this stress of 200 MPa is acting is 1,3 Joule. Take E = 200 GPa Calculate : The load The length of the square portion of the bar The load that falls from a height of 8 mm and induces 1,3 Joules in the bar
Two cylindrical copper alloy bars have the same length L, but different shapes, as can be seen in the figure. The two bars are subjected to the same axial load P. Use the following numerical data: P = 1400 kN, L = 5 m, d = 80 mm, E = 110 GPa, and ν = 0.33. (a) Find the change in length of each bar. (b) Find the change in volume of each bar.
In the figure, a solid copper rod with an expansion coefficient α copper = 165.10-7 1/ºC is 20 mm in diameter. It is placed in a steel pipe with an outer diameter of 30 mm with an inner diameter of 2 mm larger than this bar and an expansion coefficient αsteel = 125.10-7 1/ºC, and is combined with a rigid plate from the top so that they move together. Find the stresses that will occur in steel and copper when the system is heated with a temperature difference of Δt = 80 ºC. (Esteel=200 GPa, Ecopper=100 GPa)

An aluminum right-circular cylinder surrounds a steel cylinder as shown in the figure. The axial compressive load of 200 kN is applied through the rigid cover plate shown. If the aluminum cylinder is originally 0.25 mm longer than the steel before any load is applied, find the normal stress in each when the temperature has dropped 20 K and the entire load is acting. For steel take E = 200 GPa, ? = 12 × 10–6 /°C, and for aluminum assume E = 70 GPa, ? = 25 × 10–6 /°C.
