Weight sensitivity

-

The sensitivity of the balance is the angle a to which the balance of the balance is shifted from the equilibrium position (zero position) when the difference between the weighing units is unitary (usually 1 mg). With careful weighing, we want the slight change in load to cause the tip to tip as wide as possible.

C from u l O s c . w a g i = a P {displaystyle Sensitivity = {\ frac {a} {P}}}

The sensitivity is directly proportional to the length of the beam arms P and inversely proportional to the beam's weight and the center of gravity of the beam and the direction of its axis of rotation.
