asked Sep 22, 2022 in Machine Dynamics by Grayson (34.3k points)

In which of the following cases Klein’s construction can be used?

(a) Crank has a uniform angular velocity

(b) Crank has a uniform angular acceleration

(c) Lever has a uniform angular acceleration

(d) When the motion is SHM

This question was posed to me in an interview for internship.

This intriguing question comes from Klien’s Construction topic in division Inertia Forces in Reciprocating Parts of Machine Dynamics

The correct answer is (a) Crank has a uniform angular velocity

Explanation: Klein’s construction can be used in both the cases, i.e when the crack has both uniform and non uniform angular velocity and is independent of this condition.

An Internal combustion engine has a connecting rod of mass 2 kg and the distance between the centre of crank and centre of gudgeon pin is 25 cm. The Center of Gravity lies at a point 10 cm from the gudgeon pin along the line of centres. The radius of gyration of this system about an axis through the Center of Gravity perpendicular to the plane of rotation is 11 cm. If two masses are used instead of the connecting rod, one at the gudgeon pin and other at the crank pin. What will be the new radius of gyration?
