Answer to Problem 8PP

Angular impulse L=2.45 kg-m2/s and average torque τ=1.02 N-m

Explanation of Solution

Given:

Angular velocity, ω=70 rad/s

Moment of inertia, I=0.0350 kg-m2

Time interval, Δt=2.4 s

Formula used:

Angular impluse is given as,

  L=Iω  (1)

Here, L is angular impulse, I is moment of inertia and ω is angular velocity.

Also,

  L=τΔt  (2)

Here, τ is torque and Δt is time interval

Calculation:

Substitute the value of I and ω in equation (1).

  L=0.0350×70=2.45 kg-m2/s

Now, substitute the value of L and Δt in equation (2).

  2.45=τ×2.4τ=2.452.4=1.02 N-m

Conclusion:

Therefore, angular impulse is equal to 2.45 kg-m2/s and average torque is 1.02 N-m .
