A steel ring is to be fitted on a wooden disc of radius R and thickness d. The inner radius of the ring is r which is slightly smaller than R. The outer radius of the ring is r + b and its thickness is d (same as the disc). There is no change in value of b and d after the ring is fitted over the disc, only the inner radius becomes R. If the Young’s modulus of steel is Y, calculate the longitudinal stress developed in it. Also calculate the tension force developed in the ring.
[Take `b lt lt r`]

Text Solution

Verified by Experts

The correct Answer is:
`Y((R-r)/(R)); Ybd ((R-r)/(r))`
