NettetThe angular acceleration of a body which is rotating about a fixed axis is given by α = − kω2, where the constant k = 0.1 (no units). Determine the angular displacement and time elapsed when the angular velocity has been reduced to one-third its initial value ω0 = 12rad / s. Narayan H. Numerade Educator 06:31 Problem 11 Nettet6. aug. 2024 · 13.S: Rigid-body Rotation (Summary) Douglas Cline. University of Rochester. 1. A hollow spherical shell has a mass m and radius R. Calculate the inertia tensor for a set of coordinates whose origin is at the center of mass of the shell. Now suppose that the shell is rolling without slipping toward a step of height h, where h < R.

NettetTo increase the moment of inertia of a body about an axis, you must (a) increase the angular acceleration. (b) increase the angular velocity. (c) decrease the angular velocity. (d) make the body occupy less space. (e) place part of the body farther from the axis. The moment of inertia is proportional to R 2; hence, to increase I at fixed mass, the NettetRotation of Rigid Bodies 1 Angular Velocity and Acceleration = s r (angular displacement) The natural units of is radians. 1 rad = 360o 2ˇ = 57:3o Angular Velocity Usually we pick the z-axis as the direction about which the rigid body rotates.! = t (average angular velocity)!= lim t!0 t = d dt (de nition of angular velocity) NettetUsage examples of axis.
