Unformatted text preview: virtual work to determine the vertical deflection at point A corresponding to the equilibrium configuration. Assume that displacements are small. Problem 3 Using the principle of virtual work, find the angle at equilibrium. Each member of the linkage is rigid. Assume all displacements are small. Problem 4 Find the forces in each of the four springs, in terms of P and , using the principle of virtual work. Assume all displacements are small....
