Question:
A machine component slides along a horizontal bar at A and moves in a vertical slot at B. The component is represented as a rigid bar AB (length L = 1.5m, weight W = 4.5 kN) with roller supports at A and B (neglect friction). When not in use, the machine component is supported by a single wire (diameter d = 3.5 mm) with one end attached at A and the other end supported at C, as shown in the figure. The wire is made of a copper alloy; the stress-strain relationship for the wire is
- Plot a stress-strain diagram for the material; what is the modulus of elasticity E (GPa)? What is the 0.2% offset yield stress (MPa)?
- Fin the tensile force T (kN) in the wire.
- Fin the normal axial strain and elongation (mm) of the wire.
- Find the permanent set of the wire if all forces are removed.
