Magnitude of Angular Momentum of L Bar

A rigid, uniform bar with mass m and length b rotates about the axis passing through the midpoint of the bar perpendicular to the bar. The linear speed of the end points of the bar is v. What is the magnitude of the angular momentum L of the bar?
Express your answer in terms of m, b, v, and appropriate constants.

Solution Preview

Given, the length of the bar is b.
The end point of the bar is moving with tangential speed v.
The radius of rotation of this ...

Solution Summary

Angular velocity and moment of inertia are computed first to compute the angular momentum.
