A rod of length l tapers uniformly from a diameter D at one end to diameter d at other end as shown in Figure 12.8. Considering an small element of thickness dx at distance x from the end of diameter d, the diameter of the element is calculated as  Figure 12.8 Extension in Taper Rod Example 12.4: A rod tapers uniformly from 50 to 20 mm diameter in a length…

Hooke’s law states that stress and strain are proportional to each other under elastic limit. Originally, Hooke’s law specified that stress was proportional to strain but later Thomas Young introduced constant of proportionality which is known as Young’s modulus of elastic. Further, this name was superseded by modulus of elasticity. Figure 12.3 demonstrates the Hooke’s Law. Figure…

There are certain behaviours of all materials under the influence of external force. Stress and strain are one of the measures to show these behaviours. Stress is a resistive force per unit area, which is developed internally to oppose the external force subjected to the material. Strain is a measure of deformation of the material…
