Relativity of Time

Where physics meets philosophy... There is another view on the relativity of time: 
Growing older is mandatory.  
Growing up is optional.
Just a thought dedicated to my students.

Torque

The picture above shows two masses in an equilibrium. Physicists see this situation through the lenses of forces and their respective arms (an arm is the distance from pivot point to the point where the force is exerted).
 counterclockwise torque (the left side) = 26 cm * 100 g = 2600 cm*g
clockwise torque (the right side) = 13 cm * 200 g = 2600 cm*g
