Question

The relationship between Φ and θ is given by?

(a) SinΦ=\(\frac{sin\theta}{L/r}\)

(b) CosΦ=\(\frac{sin\theta}{L/r}\)

(c) SinΦ=\(\frac{sin\theta}{L\times r}\)

(d) CosΦ=\(\frac{cos\theta}{L/r}\)

I got this question in an online interview.

My question is from IC Engine in portion Design of IC Engine Components of Automotive Engine Design

Answer 1

Correct option is (a) SinΦ=\(\frac{sin\theta}{L/r}\)

Explanation: The relationship between Φ and θ is given by SinΦ=\(\frac{sin\theta}{L/r}\) where L is the length of the connecting rod and r is the radius of the crank.
