Conduction and Convection

When energy travels from one object to another it is said to have undergone heat transfer. Heat transfer is nothing but the transfer of thermal energy or internal energy from one thing to another, like e.g., when a vessel with water, kept on top of a burner, heats up because of the flame underneath it.

The metallic hollow pipe shown in Figure Q1 is fixed at both its ends, and is under axial compression. The pipe has an external diameter D = 74 mm, an internal diameter d = 49 mm, and a length L = 5.06 m. The Young's Modulus of the metal used to manufacture the pipe is: E = 157.59 GPa.

# 2-12. Normal Strain in rods constrained by walls with misfit Rods (1) and (2) were supposed to fit exactly between the rigid walls at A and C, as indicated in the figure below. However, rod (2) was manufactured a small amount, 8L, too long. A technician decides to lower the temperature of rod (2) by AT so that he can insert it in the space between B and C. When rod (2) returns to its initial temperature, the length of each rod is no longer the same as the original one, and the resulting strain is often called "residual strain"".
