GATE 2026 ME – Question 16

Engineering Mechanics · Kinematics and dynamics of rigid bodies in plane motion · 1 mark · Multiple choice

A horizontal disk has a radial frictionless slot in which a small block is confined to slide. The disk turns anticlockwise about its centre with a constant angular velocity of 3 rad/s. If the block slides along the slot with a constant speed of 0.2 m/s relative to the slot, then the magnitude of Coriolis acceleration in m/s$^2$ is

  1. 1.2
  2. 0.6
  3. 2.4
  4. 0.3

Show answer and explanation

Correct answer: (A) 1.2

Explanation

The Coriolis acceleration has magnitude $2\omega v_{rel} = 2 \times 3 \times 0.2 = 1.2$ m/s$^2$.
