Problem 1. A shaft cut from steel (E=210 GPa) has two cylindrical sections with the diameters shown and is fixed to a wall on the left side. A compressive load of 1.2 kN is applied to the free end and an additional 2.0 kN load is applied to the "shoulder" (i.e., the exposed area at the change in diameter). Determine the total change in length of the shaft (i.e., 8c/A). You can either find the change in length of each segment, or you can use superposition to find the change in length caused by each force. 2.0kN 1.2kN $18mm A 34mm B C K * K- 110mm 60mm
