1. The designers of lamp mechanisms, such as that shown in the figure, usually rely on joint friction to aid in maintaining static equilibrium. For the present problem, assume that sufficient friction exists

2. Calculate the x- and y-components of all forces acting on each member of the loaded frame.
At point C to prevent rotation there, but ignore friction at all other joints. If the mass of the lamp fixture is 0.6 kg with mass center at G, determine the spring force FS necessary for equilibrium in the position shown.
