A point is moving at the end of the link rotating with constant angular velocity ω, what will be the value of radial component of acceleration?

(a) 0

(b) ω^2R

(c) Infinite

(d) ω^2R/2

The question was posed to me in an international level competition.

Question is taken from Acceleration in the Slider Crank Mechanism & Coriolis Component in portion Acceleration in Mechanisms of Machine Kinematics

by (106k points)
Correct option is (b) ω^2R

The best I can explain: Any point at the end of the link which is moving with a constant angular velocity has no component as tangential acceleration, it only possess radial component of acceleration whose value is given by ω^2R, where R is the distance of the point from the reference point.
