A thin U-shaped member is kept in equilibrium in the vertical plane by up to three fingers and the cord (gravity acts
downward). The weight of the member is uniformly distributed with 0.1 lb/in. So the total weight is 17.5 lb. Neglect the
thickness of the member and any friction between the fingers and the member. Assume the finger force at G is zero.
Determine the cord force and the other finger forces.
