Homework Equations



Using Compatibility Equation & Prinicipal of Superpositon to find Reaction force at C.
Using Principal of Superposition and Maxwell Reciprocal Theorem, to find out Reaction force at C. State experiment procedures.


The Attempt at a Solution



I know there are 3 unknown forces Ra,Rb and Rc. and only 2 equilibirum equations of Rotational and Vertical/Horizontal. But ive no idea how to attempt to find the compatibility equation, any tips? I know that principal of superpostion means that when u clamp 1 side and put 2 different forces with 2 different deflections, u add them up and that is the defelection for the force added from the 2 difference forces. But how am i suppose to find the reaction force at C when the sides are not even clamped?


Help help help! i really dont know where to start with and how to solve this problem. any tips will be greatly appreicated.

Are you familiar with the force method? There is a tutorial on it in the Math & Science Tutorials section.
