Figure shows the stress versus strain plot for a material that is stretched by a machine pulling in opposite directions at the two ends of the wire. The wire has an initial length of L in meter and an initial cross-sectional area of A in meter-square. How much work does the force from the machine do on the wire to ?produce the strain stress 0 0 strain .
The figure shows an approximate plot of stress versus strain for a spider-web thread, out to the point of breaking at a strain of 2.25. The vertical axis scale is set by a = 0.130 GN/m2,b = 0.500 GN/m2, and c = 0.720 GN/m2. Assume that the thread has an initial length of 0.840 cm, an initial cross-sectional area of 4.00 × 10-12 m2, and (during stretching) a constant volume. The strain on the thread is the ratio of the...
Question 4 1 pts A wire made from a composite material is shaped into a cylinder and is stretched by a machine pulling in opposite directions at the two ends of the wire. The wire has an initial length of 1.20 m and an initial cross-sectional area of 9.00 x 10-6m2. If a force of 450 N stretches it by 2.1 mm and the wire returns to its original shape after being stretched, what is the Young's Modulus of the...

Figure < 1 of 1 Consider, for instance, a bar of initial length L and cross-sectional area A stressed by a force of magnitude F. As a result, the bar stretches by AL (Figure 1) Let us define two new terms: • Tensile stress is the ratio of the stretching force to the cross-sectional area: stress = 5 • Tensile strain is the ratio of the elongation of the rod to the initial length of the bar strain= 41 It...
Please give a full, detailed, worded explanation. Thank you :))) S. Draw a possible stress strain graph for a material with a yield stress of 300 MPa, an elastic modulus of 200 GPa, a UTS of 450 MPa and a ductility of 20%. Calculate the elastic strain at the point where the material starts to plastically deform. 6. A nylon rope with an elastic modulus of 3 GPa is placed under a force of 17.5 kN. The cross-sectional area of...
