Addendum is the height of the tooth above the pitch circle in a gear.

• Addendum is the distance between the pitch circle and the top of the gear tooth.

• It is an important parameter in gear design as it affects the strength and durability of the gear.

• The addendum can be calculated using the formula addendum = module or diametral pitch.

• For example, in a gear with a module of 2mm, the addendum would be 2mm.

The least count of vernier calipers is the smallest measurement that can be accurately read on the scale.

• The least count is determined by the number of divisions on the main scale and the vernier scale.

• It is calculated by dividing the smallest division on the main scale by the number of divisions on the vernier scale.

• For example, if the smallest division on the main scale is 0.1 mm and the vernier scale has 10 division
