A steel cable is used to lift a load W with the following given. weight W = 175 kN diameter = 30.03 mm length = 12.02 mm E = 200 GPa 1. Find elongation. 2. Find strain. 3. What is the ductility of material in percentage given that steel cable fails at 27.50 mm diameter. Please make sure your handwriting is readable.

W A L A Test beam Strain gauge (a) Unsymmetrical cantilever beam with weight applied at the free end and at the "shear centre", so that there is no torsion induced. Section A-A Strain gauge 1 b Strain gauge 3 Strain gauge 2 B (b) Location of Huggenberger strain gauges a Referring to the above figure, calculate the location of the centroid, the second moments and product of area for the cross-section if; D = 67 mm B = 41 mm t = 2.41 mm. From these, calculate the position and orientation of neutral axis for pure bending in the vertical plane (i.e. bending about a horizontal axis). Also calculate the directions of the principal second moments of area. Next, graph as scale diagram of the cross-section and plot the neutral axis on that diagram in the correct location and indicate the direction of deflection for the same conditions

Two [0°, 45°, 90°] strain gauge rosettes are placed along the neutral axis of a 4-point bent beam as shown in the figure below. What will the strain reading in each of the 6 gauges be? P L/3 L/3 -45° 45 L/4 L/2 L NA h
