Find the appropriate unit for h (heat transfer coefficient).

Question

The lower ends of the three bars shown in the figure are at the same level before the rigid homogeneous W = 100 kN block is attached. The properties of the bars are shown in the table. Steel Bronze Length, L Area, A Modulus of elasticity, E Coefficient of thermal expansion, a 1.00 m 500 mm? 1.60 m 900 mm 200 GPa 83 GPa 11.7x106 /°C 18x10 /°C Bronze Steel Steel W 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?

3. An aluminum material element experiences a state of plane stress with the magnitudes and directions of the stress components given in the figure. Please calculate the change in volume per unit volume this material element would experience when subjected to the stress state given in the image below and a temperature increase of 80°C. (Note that the dotted horizontal line and 15 degree angle are irrelevant to this problem). Aluminum Properties: Thermal Coefficient of Expansion = 24 x 10-6 mm/mm/°C, Elastic Modulus = 69 GPa, Poisson Ratio = 0.35 250 MPa 60 MPa 15° 150 MPa

There is no force on a beam, but the beam is subjected to a very large temperature difference above and below. As shown in the figure below, try to calculate the vertical displacement of the midpoint of the beam, assuming that the temperature coefficient of the entire beam is a = 11.7×10^-6 °F.
