The temperature of the bars is then increased by 80°C. The block is assumed to
remain horizontal after all deformations have occurred.
Which of the following most nearly gives the stress developed in the steel bar?
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?
5.) When an aluminum cookie sheet is placed in an oven and heated up, it expands due to the
temperature change. The change in area of the cookie sheet is modeled using the
following equation:
AA = A,YAT
where
A4 = change in area in in?
original area in in?
y = area coefficient of thermal expansion
AT = change in temperature in F°
What is the appropriate unit for y if the preceding equation is to be homogeneous in units?
