Question

In the given figure, the direction of radial velocity vector and angular velocity is given what will be the direction of coriolis force?

(a) Along the radial velocity vector

(b) Opposite to radial velocity vector

(c) Perpendicular to radial velocity vector towards right

(d) Perpendicular to radial velocity vector towards left

This question was posed to me during a job interview.

Query is from Acceleration in the Slider Crank Mechanism & Coriolis Component in section Acceleration in Mechanisms of Machine Kinematics

Answer 1

Right option is (d) Perpendicular to radial velocity vector towards left

Best explanation: The direction of the coriolis component of acceleration is obtained by rotating the radial velocity vector by 90 degrees in the direction of the angular velocity.
