I got this question by my school teacher while I was bunking the class.

Question is taken from IC Engine in portion Design of IC Engine Components of Automotive Engine Design

Answer 1

The correct choice is (a) 80mm

The explanation is: IP=\(\frac{plAn}{60}\)

                        4600=(0.35×l×9852.3×1000)/60

                                l=80mm
