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 weight, with an unknown mass, falls through a distance of 10 millimeters (mm) onto a collar attached to the bottom end of a vertical bar. The bar is 3 meters (m) long and has a cross-sectional area of 600 square millimeters (mm2). The impact causes the bar to instantly stretch by 2 mm. The Young's modulus of the bar material is 200,000 MPa. Determine: 1. The weight of the falling object. 2. The stress experienced by the bar due to the impact.
