To calculate angular acceleration for Link BD and ED, you need to use the formula: α = (ω2 - ω1) / (t2 - t1), where ω2 and ω1 are the final and initial angular velocities respectively, and t2 and t1 are the final and initial times respectively.
The unit of measurement for angular acceleration is radians per second squared (rad/s2).
To verify the solution for calculating angular acceleration, you can use the formula: α = Δω / Δt, where Δω is the change in angular velocity and Δt is the change in time. You can also check if the units of measurement are correct.
The accuracy of the calculated angular acceleration can be affected by factors such as measurement errors, friction, and external forces acting on the object.
Yes, angular acceleration can be negative. A negative angular acceleration indicates that the object is slowing down or decelerating.
