Question

Toggle the supports back on. With the 20 kg mass still in the same position, iterate the position and amount of mass on the right side to find another condition that balances the lever

Answer 1

/T

Torque =(perpendicular component of force vector ) X (distance from the axis )

for rotational equilibrium Torque should be balanced.

Now we calculate torque /
