Question 3 1 pts Castigliano's theorem states that when forces act on elastic systems subject to small displacements, the displacement corresponding to any force, in the direction of the force, is equal to the partial derivative of the total strain energy with respect to that force. Castigliano's theorem can be used a) to find the deflection at a point even though no force or moment acts there b) to solve statically indeterminate problems c) both a & b d) neither a c d b
