Questions
Fоr rоd AB, the crоss section аreа is 1 × 10-3 m2, Young's modulus is 200 GPа and the length is 2 m. For rod BC, the cross section area is 0.5 × 10-3 m2, Young's modulus is 100 GPa and the length is 1 m. Force FD = (120 + x) kN is applied at the midpoint D of the rod AB. Force FC is applied at free end C. Directions of the forces are shown in the figure. What is the magnitude of FC should be applied so that the displacement at point B is 0. Please enter your calculated magnitude of Force FC in the box below.
