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 2.05. The vertical axis scale is set by a = 0.130 GN/m²,b = 0.460 GN/m², and c = 0.840 GN/m². Assume that the thread has an initial length of 0.780 cm, an initial cross-sectional area of 8.00 × 10^-12 m², and (during stretching) a constant volume. The strain on the thread is the ratio of the change in the thread's length to that initial length, and the stress on the thread is the ratio of the collision force to that initial cross-sectional area. Assume also that when the single thread snares a flying insect, the insect's kinetic energy is transferred to the stretching of the thread. a) How much kinetic energy would put the thread on the verge of breaking? What is the kinetic energy of b) a fruit fly of mass 6.50 mg and speed 1.90 m/s and c) a bumble bee of mass 0.400 g and speed 0.360 m/s? Would d) the fruit fly and e) the bumble bee break the thread?

The graph shows a= 0.700, b= 1.40, c= 2.05.

The figure represents an insect caught at the midpoint of a spider-web thread. The thread breaks under a stress of 9.2 × 108 N/m2 and a strain of 2.00. Initially, it was horizontal and had a length of 3.5 cm and a cross-sectional area of 9.5 × 10-12 m2. As the thread was stretched under the weight of the insect, its volume remained constant. If the weight of the insect puts the thread on the verge of breaking, what is...

The figure shows a plot of potential energy U versus position x of a 0.250 kg particle that can travel only along an x axis under the influence of a conservative force. The graph has these values: UA = 9.00 J, UC = 20.0 J and UD = 24.0 J. The particle is released at the point where U forms a “potential hill” of “height” UB = 12.0 J, with kinetic energy 8.00 J. What is the speed of the...

For each of the following pairs of polymers, plot and label schematic stress-strain curves on the same graph [i.e. make separate plots for parts (a), (b) and (c)]. (a) Polychloroprene rubber having a number-average molecular weight of 100,000 g/mol and 15% of available sites cross-linked; liner polypropylene having a number-average molecular weight of 150,000 g/mol.

Consider the brass alloy the stress-strain behavior of which is shown in the Animated Figure 6.12. A cylindrical specimen of this alloy 19 mm in diameter and 177 mm long is to be pulled in tension. Calculate the force necessary to cause a 0.00969 mm reduction in diameter. Assume a value of 0.34 for Poisson's ratio.

(c) Draw a schematic graph of resolved shear stress versus shear strain for a single crystal of a pure metal. Clearly label the point of the critical resolved shear stress and the three subsequent stages of dislocation behaviour. Describe these three stages. (d) Explain why the critical resolved shear stress is much lower than the theoretical strength, based on the force required to break atomic bonds within the structure.
