A heat sink is supported by three posts made of A-36 steel and brass, as shown in the figure. The sink is subject to a uniform loading of 50 kN/m along its 800 mm length. The circular posts have a length of 400 mm when no load is applied to the bar, and the temperature is 20 degrees Celsius. Complete the following tasks: 1) Determine the force supported by each post if the bar is subjected to a distributed load and the temperature is raised to 100 degrees. The heat expansion coefficient of brass is 18 x 10 m/mC and of A-36 steel is 12 x 10-6 m/mc. The modulus of elasticity for A-36 steel is 200 GPa and for brass is 110 GPa. 2) Determine whether the posts will enter the plastic region or not. The yield strength of A-36 steel is 250 MPa and for brass is 95 MPa. Justify your answer with calculated values. 30 mm Steel 800 mm 50 kN/m 50 mm Brass 400 mm Steel

The depicted in the figure below has a length of 0.635m and a diameter of 50mm. The bar is made of a copper alloy with an elastic modulus E = 110 GPa and a linear thermal expansion coefficient a = 17.5 × 10-6/°C. The bar is initially positioned at room temperature with a gap of 0.2mm between end A and the rigid wall. The bar's right end at B is supported by an elastic spring of negligible thermal expansion coef- ficient and a spring constant of k = 210 × 10°N/m. A small gap maintained between the copper bar and the smooth surrounding sleeve facilitates frictionless motion as the bar thermally expands.
