The assembly shown consists of a light rigid bar AB, pinned at 0, that is attached to the steel and aluminum rods. In the position shown, bar AB is horizontal and there is a gap, A = 7 mm, between the lower end of the steel rod and its pin support at C. The stress in the aluminum rod (in MPa) when the lower end of the steel rod is attached to its support is: Eal= 70 GPa, Est 200 GPa. Aa 240 mm2, A= 170 mm?. 0.75 m 1.5 m Aluminum L= 2 m Steel

A light ridig member AB is pinned at A and is further supported by light elastic rods CD and GF, member AB supports a 5000lb load at B the elastic modulus for the two elastic rods CD and GF is given as E= 30x106 psi and the cross-sectional area for each of these rods is 1 in2. what are the forces in the two supporting elastic rods as a results of the loading?
A steel beam is used in the roadbed of a bridge. The beam is mounted between two concrete supports when the temperature is 23 °C, with no room provided for thermal expansion. What compressional stress must the concrete supports apply to each end of the beam, if they are to keep the beam from expanding when the temperature rises to 42 °C? Assume that the distance between the concrete supports does not change as the temperature rises.
