Three storey building A three-storey steel column in a building supports roof and floor loads as shown in the figure below. The storey height His 3 m, the cross-sectional area A of the column is 7500 mm2, and the modulus of elasticity of the steel is 200 GPa. Calculate the magnitude of the total shortening of the column, assuming P, = 1832 kN and P2 = 1681 kN, and P3 = 2196 kN. provide your answer in mm and to...
The composite cantilever shown below is made of three plates: two external ones are made of steel and the middle one is made of copper. The length of the cantilever is 2m, the width is 50mm, and the thickness of each plate is 20mm. Determine the axial force induced in the copper plate when the temperature of the cantilever rises by 77°C. Young's modulus for steel can be taken as 200GPa and the coefficient of thermal expansion as 11x10-6mm/(mm oC)....
