Sorry but i dont know i was doing this for some point sorry
Pulling the two ends of a rubber band further and further apart from each other.
Answer:
The magnitude of the angular acceleration is α = (3 * F)/(M * L)
Explanation:
using the equation of torque to the bar on the pivot, we have to:
τ = I * α, where
I = moment of inertia
α = angular acceleration
τ = torque
The moment of inertia is equal to:
I = (M * L^2)/3
Also torque is equal to:
τ = F * L
Replacing:
I * α = F * L
α = (F * L)/I = (F * L)/((M * L^2)/3) = (3 * F)/(M * L)
