To determine The magnitude of the average torque. Explanation Refer figure 1. Write an expression for magnitude of change in angular momentum . | Δ L → | = Δ L x + Δ L y = ( L sin θ ) 2 + ( L cos θ − L ) 2 = L ( sin θ ) 2 + ( cos θ − 1 ) 2 = ( I ω ) ( sin θ ) 2 + ( cos θ − 1 ) 2 = ( 1 2 m r 2 ) ( ω ) ( sin θ ) 2 + ( cos θ − 1 ) 2 (I) Here, | Δ L → | is the magnitude of change in momentum, Δ L x is the horizontal component of Δ L , Δ L y is the vertical component of Δ L , L is the angular momentum, θ is the angle, m is the mass, r is the distance from rotational axis, I is the moment of inertia and ω is the angular velocity. Write an expression to calculate the torque. τ = | Δ L → Δ t | = | ( 1 2 m r 2 ) ( ω ) ( sin θ ) 2 + ( cos θ − 1 ) 2 Δ t | (II) Here, τ is the torque and Δ t is the time

Angular Momentum

The momentum of an object is given by multiplying its mass and velocity. Momentum is a property of any object that moves with mass. The only difference between angular momentum and linear momentum is that angular momentum deals with moving or spinning ob…

Moment of a Force

The idea of moments is an important concept in physics. It arises from the fact that distance often plays an important part in the interaction of, or in determining the impact of forces on bodies. Moments are often described by their order [first, second…
