Question

In the formula P=Pccos∅, what is Pc?

(a) The pressure acting on the camshaft

(b) Force acting on the camshaft

(c) The pressure acting on connecting rod

(d) Force acting on connecting rod

This question was posed to me during an interview.

I want to ask this question from IC Engine topic in chapter Design of IC Engine Components of Automotive Engine Design

Answer 1

In the formula P=Pccos⁡ϕP = P_c \cos \phiP=Pc​cosϕ, PcP_cPc​ typically refers to the force acting on the connecting rod. The formula represents the projection of the force on the connecting rod (denoted by PcP_cPc​) in the direction of a specific angle $\varphi$ (such as the angle between the crank and the connecting rod).

Final Answer:

(d) Force acting on connecting rod.
