"A Newtonian fluid has viscosity that does NOT change." True False

The band in the figure below is stainless steel (coefficient of linear expansion = 17.3 ✕ 10−6°C−1; Young's modulus = 18 ✕ 1010 N/m2). It is essentially circular with an initial mean radius of 5.4 mm, a height of 4.4 mm, and a thickness of 0.51 mm. If the band just fits snugly over the tooth when heated to a temperature of 81°C, what is the tension in the band when it cools to a temperature of 37°C?

A 1-m long steel bar (E = 200 GPa) of 10 x10 mm dimension fixed at one end and free at the other end is heated to 90°C from initially 30°C. What is the normal stress, in MPa, induced in the system due to change in temperature? Use a = 12 x 10-6 per °C. Encode you answer in whole number. Round your answer to 0 decimal places.

A 4 meter long steel plate with a rectangular cross section (10 mm x 50 mm) is resting on a frictionless surface under the sun. The plate temperature is measured to be at 40°C. The plate is then moved into a cold room and is left to rest on a frictionless surface. After several hours, the plate temperature is measured to be 5°C. The steel has a modulus of elasticity equal to 200 GPa and a coefficient of thermal expansion equal to 1.1x10-5/°C. a. What is the length of shrinkage b. What tension load is needed to return the length to the original value of 4 meters? c. What is the longitudinal strain under this load?
