Solution: (a) Equation of motion for rotation gives that change in angular momentum per second is the average torque acting on the flywheel. The change in angular momentum of the flywheel in 1.50 s is (0.800-3.00) kg m2/s. Therefore, the average torque acting on the flywheel during this period will be 1.5 2.2 − kg m 2 s -2 = − 1.46 N m.

2. Decompose F into components parallel and perpendicular to r, and take: t = rF. ┴. If rotation is clockwise, torque is negative, and if rotation is counterclockwise torque is positive. Note: If F and r are parallel or antiparallel, the torque is 0. (e.g., can’t open a door if pushing or pulling toward the hinges)

Duffy_EP_2013_ch10. Answer to Essential Question 10.6: The correct ranking is 3>1>2. In the rotational inertia equation, the distance from the axis to the ball (the length of the rod) is squared, while the mass is not. Thus, changing the length by a factor of 2 changes the rotational inertia by a factor of 4, whereas changing the mass by a ...

F = ma. (Equation 1.0) If we consider rotational motion, we find that a single unbalanced torque, τ, produces an angular acceleration, α, which depends not only on the mass of the object but on how that mass is distributed. The equation which is analogous to F = ma for an object that is rotationally accelerating is: τ = Iα.
