I need the answer as soon as possible
Q2 the assembly in the figure below consists of a rigid bar AB (having a negligible mass) pinned at O and attached to the aluminium rod and the steel rod. In the position shown, the bar AB is horizontal and there is a gap A = 0.5 mm. this gap is between the lower end of the aluminium rod and its pin support at D. Find: a) Find the temperature change in the steel and aluminium rods when the lower end of the aluminium rod is pinned to the support at D. b) After pinning the aluminium rod with the support D, the rods temperature went back to the room temperature, find the stress in the steel rod. Steel B A A=200mm? Aluminium 0.6 m 1.2 m A=300mm? E=200Gpa E=70Gpa a=23*106 m/(m. C) D L=2.5m a,=11.7 *106 m/(m. C) A=0.5mm
