Graphing the Rotational Inertia of an Irregular Shape
We determine what data to collect to create a graph with rotational inertia as the slope of the best-fit line. Then we collect the data and determine the rotational inertia of an irregular shape.

Pulleys and Tension in static equilibrium Summary
If a pulley is in static equilibrium and the following is true: 1) Rope is massless 2) Pin is frictionless Then the tension in the cable will be constant everywhere along the cable. There is only 1 force (tension) that is internal in the...
