Which of the mentioned below is the Rankine’s formula?(a) Pcr=\(\frac{A}{1+a(\frac{L}{K_{xx}})}\)(b) Pcr=\(\frac{\sigma_cA}{1+a(\frac{L}{K_{xx}})}\)(c) Pcr=\(\frac{A^2}{1+a(\frac{L}{K_{xx}})}\)(d) Pcr=\(\frac{\sigma_cA^2}{1+a(\frac{L}{K_{xx}})}\)I got this question by my college professor while I was bunking the class.I'm obligated to ask this question of IC Engine in section Design of IC Engine Components of Automotive Engine Design

Answer»

The CORRECT option is (b) Pcr=\(\frac{\sigma_cA}{1+a(\frac{L}{K_{xx}})}\)

Explanation: The Rankine’s formula is given by Pcr=\(\frac{\sigma_cA}{1+a(\frac{L}{K_{xx}})}\) where pc is the force on connecting rod, A is the cross-sectional area, L is the length of connecting rod, a is end FIXITY COEFFICIENT, σc is stress and Kxx is the RADIUS of gyration.
