Torque and equilibrium of a rigid body (see-saw)
A uniform beam on a pivot with adjustable masses. Slide the masses and the pivot, check ΣF = 0 and Στ = 0, find the balance point, and see the beam tilt with angular acceleration when torques are unbalanced.

What you do in the lab
Change the controls and watch the physics behave in real time in 3D. Live readouts and graphs show the numbers behind it, and the Learn tab has the theory, procedure, observations and viva questions. Works on a phone or a laptop, in English and Hindi.
