(a) 2 to 4mm

(b) 3.5 to 4.5mm

(c) 2.6 to 4mm

(d) 3.6 to 4mm

The question was posed to me in a national level competition.

Asked question is from IC Engine topic in chapter Design of IC Engine Components of Automotive Engine Design

Answer 1

Right option is (c) 2.6 to 4mm

Best explanation: Thickness of ribs is given by tr=\(\frac{t_h}{3}to\frac{t_h}{2}\)

 =\(\frac{8}{3}to\frac{8}{3}\)

 = 2.6 to 4mm
