# Problem: What is the magnitude of the angular momentum of the 830 g rotating bar in the figure (Figure 1) ?What is the direction of the angular momentum of the bar ?

###### FREE Expert Solution

Angular momentum:

$\overline{){\mathbf{L}}{\mathbf{=}}{\mathbf{\omega }}{\mathbf{I}}}$

Angular speed in rad/sec is given by:

ω = (120)(2π)/60 = 12.567 rad/s
