The bars of the truss each have a cross sectional area of 700 mm2. Determine the average normal stress in members BC, BG, and BH. State whether the stress is tensile or compressive.

A body is said to be in equilibrium if the system of forces acting on the body tends to keep the body at rest, in other words, there is no translation motion or net torque on the body. Under such conditions, the equilibrium conditions are to be applied t…
