Two bars are held together by 6 bolts. Bar 1 has a modulus of E, a cross-sectional-area of A, and a length of L/2. It has a force of 2P acting axiallyon itat L/4, directed to the left. It is held in place by a rigid wall to it's left.
Bar 2 is located to the right ofBar 1 and the two are connected by 6 bolts. Bar 2 has a modulus of E, a cross-sectional-area of A/2, and a length of L/2. It has a force of 3P acting axially on it at L/4, directed to the right. A rigid wall holds the right end of bar 2 in place.
(a) What are the formulas for the reactions at each of the walls?
(b) What are the axial displacements of the force acting on bar1, the force acting on bar2, and the center, where the two bars are connected?
