Question

Calculate the inertia force where the diameter of bolts is 10mm and σt=35N/mm^2?

(a) 5555.5N

(b) 6107.8N

(c) 6478.6N

(d) 5497.7N

The question was asked in an international level competition.

The doubt is from IC Engine in portion Design of IC Engine Components of Automotive Engine Design

Answer 1

The correct choice is (d) 5497.7N

For explanation: (Pi)max=2(\(\frac{\pi\times d_c^2}{4})\)σt

                                     =2\((\frac{\pi\times 10^2}{4})\)× 35

                                     =5497.7N
