A compound bar consists of a circular rod of steel of diameter 25 mm, rigidly fitted into a copper tube of internal diameter 25 mm and thickness 2.5 mm. If the bar is subjected to an axial load of 100 kN, find the stresses developed in the two materials. Given E = 2 x 105 N/mm² and E= 1.2 x 105 N/mm².
A vertical steel bar shown in figure Q1 is subjected to a compressive load of 75 KN. If the stress in the middle portion is limited to 47 MN/m² determine its cross-section dimensions. Find also the length of the middle and other portions if the total reduction in length of the bar is to be 0.04 mm. Assume Young's modulus for steel is 200 GN/m².

Q2/ The rigid, horizontal slab is attached to two identical copper rods. There is a gap A=0.18 mm between the middle bar, which is made of aluminum, and the slab. Neglecting the mass of the slab, calculate the stress in each rod when the temperature in the assembly is increased by 85°C. Use the following data: Each copper rod Aluminum rod A (mm²) 500 400 a (°C) 16.8 x 10-6 23.1 x 10-6 E (GPa) 120 70 Copper TA Aluminum Copper L=3m A= 1500 mm E=120 GPa a = 16.8 x 10-C Copper -750 mm-
