Answer:
156.1 rad/s = 24.8 rev/s
Explanation:
Torque = Momentum of inertial × radial acceleration = Iα
τ = 26.6 N.m
I = 0.162 kg.m²
26.6 = 0.162 × α
α = 164.2 rad/s²
Using equations of motion,
θ = 11.8 rev = 11.8 × 2π = 74.2 rad
w₀ = 0 rad/s (since the grindstone starts from rest)
w = ?
α = 164.2 rad/s²
w² = w₀² + 2(α)(θ)
w² = 0² + (2×164.2)(74.2)
w = 156.1 rad/s = 24.8 rev/s
Hope this Helps!!!

Is there any numbers to your question?
Keep in mind, the energy is conserved in a pendulum.

An analogy to explain this phenomena is the traffic explanation: Imagine you are in rush hour of traffic in a major city. Now imagine that all the traffic is only on one lane instead of being spread out on all six lanes. With more paths, there is less resistance to flow.
Your answer is: Imagine you are in rush hour of traffic in a major city. Now imagine that all the traffic is only on one land instead of being spread out on all six lanes. With more paths, there is less resistance to flow.
Have an amazing day mate!
