A rod with cross-sectional area of 100mm2 is stretched between two fixed points such that the initial tensile load is 10kN. The rod has a modulus of elasticity equal to 180 GPa and a coefficient of linear expansion of 0.00001m/m-C. The initial tension is designed such that the rod will have zero stress when there is a certain change n temperature of the rod environment. What is the temperature (in C, 2 decimal places)?

A rod with cross-sectional area of 1002 is stretched between two fixed points such that the initial tensile load is 10kN. The road has a modulus of elasticity equal to 180GPa and a coefficient of linear expansion of 0.00001m/m-°C. The initial tension is designated such that the rod will have a zero stress when there is a certain change in temperature of the rod environment. What is the temperature (in °C, 2 decimal places)?

A rigid beam BCD is supported on a roller support at C (4m from B) and has two bars AB and DE attached at each end
A rigid beam BCD is supported on a roller support at C (4m from B) and has two bars AB and DE attached at each end. The bars can carry either tension or compressive forces. The rigid beam carries a UDL of I kN/m across BC and a point load of P at D as shown in the figure above. The length of the two bars is 3000 mm. The elastic modulus of both bars is 200 GPa and the...
