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.Question 7 Find the value of The reaction force at the support A .Find the support reactions and the forces in the hinge.
