Concept:
Tangential acceleration (at):
- It acts along the tangent to the circular path in the plane of the circular path.
- Mathematically Tangential acceleration is written as
\(\overrightarrow {{a_t}} = \vec \alpha \times \vec r \)
Where α = angular acceleration and r = radius
Calculation:
Given:
α = Angular acceleration = 50 rad/s2
r = radius of crank = 50 cm = 0.5 m
Tangential Acceleration at = rα
∴ at = rα = 50 × 0.5 = 25 m/s2
