A circular rod and a 0.1-in.-thick rectangular bar are both made of a plastic material that has an elastic modulus of E = 2.3 GPa and a Poisson’s ratio of ν = 0.33. The rod and the bar are initially the same length L. After a particular load is applied, the 3.6-in.-wide rectangular bar is elongated by some amount ΔL and its width is reduced by 0.096 in. If the 1.3-in. diameter rod is stretched by the same amount ΔL, determine its change in diameter. Expansion is positive, while contraction is negative.

One spring is placed inside the other, not touching each other, and compressed between a pair of parallel plates until the distance between the plates is 40 mm. Make a neat detailed sketch of the spring and plate assembly. If G = 83 GPa for both springs, calculate the following: 1. The force applied to the spring assembly. 2. The shear stress induced in each spring. 3. The total strain energy stored in the spring assembly. 4. The stiffness of each spring. 5. The equivalent stiffness of a single spring that can be substituted in place of these springs.
A 160 mm long connecting link is 50 mm diameter for a length of 100 mm and 30 mm diameter for the remaining length of 60 mm. The gradual application of the load P results in the link storing a total of 10 J of energy. Calculate the magnitude of the applied load P, the value of the stress induced in each section and the total extension. If this load had been applied suddenly but without shock or impact, what maximum instantaneous stress would have been induced in the link? (E = 200 GPa)
