A high-density polyethylene [E = 128 ksi; α= 88 x 10-6/°F; υ = 0.4] bar is positioned between two rigid supports. The bar is square with cross-sectional dimensions of 2.50 in. by 2.50 in. and length L = 48 in. At room temperature, a gap of Δ=0.25 in. exists between the block and the rigid support at B. After a temperature increase of 120°F, determine: a) The normal stress in the bar b)The lonitudinal strain in the bar. c)The transverse (ie lateral) strain in the bar.

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.
