To calculate angular acceleration, input the values of torque and moment of inertia in the angular acceleration calculator.
This angular acceleration calculator helps to find the acceleration of a rotating body if the moment of inertia and total torque are given.
According to Wikipedia:
“Angular acceleration refers to the time rate of change of angular velocity.”
In simple words,
“It is the rotation of a rigid body about a fixed center point.”
The equation used for the calculation of angular acceleration is:
α = T/I
Where,
α represents angular acceleration,
T represents torque, and
I is moment of inertia.
The formula used in this calculator is related to tangential acceleration as:
αt = αr
Where, αt is tangential acceleration.
Example
Calculate angular acceleration if the body rotates at 30 radians per second and the moment of inertia is 10 kgm2.
Solution:
Step 1: Identify the values.
T = 30 rad s-1
I = 10 kgm2
Step 2: Put the values into the formula.
α = T/I
α = 30/10
α = 3 rad s-2
