4. The system on the right consists of three solid circular cross-section rods 1, 2 and 3. All are made from the same material with a Young's modulus of E. Forces 2P and P act at connectors C and D. Assume that as the system deforms, the connectors C and D are allowed to translate but not rotate. Assume the weight of the rods is small compared to the loads and can therefore be neglected. 1. Is this system determinate or indeterminate? 2. Write down the equilibrium force and momentum equations for connectors C and D hint: draw the FBD for C and D 3. Write the elongation equations relating the elongations to axial loads for each the three rods. 4. Write down the compatibility equations relating the elemental elongations in the rod system. 5. Solve for the axial loads in each element. State whether each element is in tension or compression. 2d (3) 3L 2P P D L 24 (2) 4d C (1) - 4d B
