Practice Problem: Torque on a Mobile

The video tutorial guides viewers through building a solar system mobile, focusing on balancing the mobile using the concept of torque. It explains how to calculate the necessary weights for each planet to achieve balance, starting with known values and using the principle of torque. The tutorial concludes with converting these weights into masses, ensuring the mobile is correctly balanced.

What is the combined weight of systems 3 through 7?

Describe how to find the mass of the planets from their weights.
