Construction and Working of Physical Balance

Construction and Working of Physical Balance
This is a device used to find the mass of an object.

Construction
It consists of a horizontal beam resting at its middle point on a central knife edge. Two similar pans are suspended on two more knife edges near each end of the beam. A long pointer is attached to the middle of the beam. There are two leveling screws on the base to level the balance on the table. The balance is used by an arresting knob in front of the balance.

Working
After leveling the balance, the object is placed in the left hand pan and the standard masses are placed
in the right hand pan. The beam is set free by turning the arresting knob. The pointer moves towards the side of the smaller mass. Standard mass in the pan is adjusted to find the mass of the object.
