Nagarjuna Construction Company Mechanical Maintenance Engineer Interview Questions and Answers

Q1. What is formula to calculate module in gears
Ans. 
The formula to calculate module in gears is the ratio of pitch diameter to the number of teeth.
• Module = Pitch Diameter / Number of Teeth

• Module is a measure of the size of the teeth on a gear.

• It is commonly used in gear design and manufacturing to ensure proper meshing of gears.

• For example, if a gear has a pitch diameter of 40 mm and 20 teeth, the module would be 40 mm / 20 = 2 mm.

Q2. Module=pitch circle dia M=D/T
Ans. 
Module is the ratio of pitch circle diameter to the number of teeth in a gear.
• Module is a gear parameter that defines the size of the gear teeth.

• Pitch circle diameter is the diameter of the imaginary circle on which the gear teeth are located.

• The formula M=D/T calculates the module where D is the pitch circle diameter and T is the number of teeth.

• For example, if the pitch circle diameter is 100 mm and the number of tee
