A steel ring at a room temperature has a radius of R, of 1.00 mm x 1.00 mm. One like to insert a bar of radius R = 2.002 cm into the ring. The following data is known for steel: 2.00 cm and a cross section area • Young Modulus E 2.00 x 1011 Pa. %3D • Coefficient of length contraction a = 1.20 x 10–5 C1 • Specific heat capacity c = 511 J.kg¬1.C-1 • Mass density p= 8050 kg.m-3 (a) What is the amount of heat needed for heating the ring so that the rod can fitted into it. (b) Assume the rod is rigid, calculate the pressure on the surface of the rod as the steel cool down to the room temperature.

A pipe is being designed to carry a fluid at a pressure of 193 MPa. In order to allow sufficient fluid flow, the internal diameter of the pipe cannot be less than 3.6 mm. Due to space constraints, the outer diameter of the pipe cannot be greater than 12.5 mm. The maximum shear stress allowed in the pipe wall is 507 N/mm². Calculate the minimum outer diameter that the pipe can have. Give your answer in mm. Your Answer:
Problem 3: (M4) Your boss at a construction company asked you to verify the thickness of a 3 m long hollow-square steel column (E=200 GPA) that can withstand an axial compressive load of 50 MN, the outer dimension a is 400 mm. The column's cross section is shown in Figure.4. Assume the column is a fixed-free type. Figure.4: Cross-section of a hollow-square steel column
