- A copper tube having a cross sectional area of 2000 mm2 and a length of 300 mm is rigidly fixed to two rigid caps on its longitudinal ends. Four steel bolts, each having a diameter of 22 mm, are symmetrically arranged parallel to the axis of the tube and are slightly fastened to the rigid caps, as well. The temperature of the assembly is then raised to 70oC. Take the elastic modulus for Copper and Steel as ECU=100 GLa and EST=200 GPa respectively; the coefficient of linear expansion for Copper and Steel as aCU=16x10-67°C and aST=12x10-6/°C respectively. Calculate the load carried by the copper tube and the load carried by each steel bolt1.7 The density of copper is 8.96 g/em'. You have three different solid samples of copper. One is rectangular with dimensions 2.3 cm x 3.1 cm x 8.0 cm. The second is a cube with edges of 3.8 cm. The third is a cylinder with a radius of 1.5 cm and a height of 8.4 ém. Calculate the mass of each sample. 1.8 A 50.00-g sample of metal at 78.0°C is dropped into cold water.
