Four axial forces are applied to the 25mm thick structural steel bar with 40mm diameter pins as shown in figure below. If the maximum allowable tensile stress in the bar is 135MPA and the maximum allowable deformation (extension or contraction) of the bar is 1.25mm, determine the minimum width, w of 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.
