Question

Calculate the thickness of the cylinder when Pmax=3MPa, D=150mm, C=4and σc=45N/mm^2.

(a) 9mm

(b) 6mm

(c) 7mm

(d) 8mm

This question was posed to me in an interview.

The above asked question is from IC Engine in section Design of IC Engine Components of Automotive Engine Design

Answer 1

The correct option is (a) 9mm

For explanation: t=\(\frac{P_{max}\times D}{2\sigma}\)+C

                         =\(\frac{3×150}{2×45}+4\)

                         =5+4

                         =9mm
