EXTENSION IN VARYING CROSS-SECTION OR TAPER ROD

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… Continue reading EXTENSION IN VARYING CROSS-SECTION OR TAPER ROD

HOOKE’S LAW

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 Further, this name was superseded by modulus of elasticity.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… Continue reading HOOKE’S LAW
