Question

A crank of radius 12cm is rotating at 60r.p.m with an angular acceleration of 50rad per sec^2.The tangential acceleration of the crank will be?

Answer 1

Answer:60cm

Explanation:

Answer 2

Answer:

Tangential acceleration is 9 m/

Explanation:

Tangential Acceleration at = rα

α = Angular acceleration = 60 rad/s2

r = radius of crank = 15 cm

∴ at = rα = 60 × 0.15 = 9 m/s

The concept of tangential acceleration is used to measure the change in the tangential velocity of a point with a specific radius with the change in time.
