The least count of Vernier caliper is the smallest measurement that can be read on the scale.

• The least count of Vernier caliper is usually 0.02 mm or 0.001 inches.

• It is determined by the number of divisions on the Vernier scale and the main scale.

• For example, if the Vernier scale has 10 divisions and the main scale has 20 divisions, the least count would be 0.1 mm divided by 200, which is 0.0005 mm.

• The least count is important for accurate measurements and should be considere...read more

10mm is equal to 10,000 microns. Other conversions include inches, centimeters, and meters.

• 1 inch = 25.4 mm

• 1 cm = 10 mm

• 1 m = 1000 mm

• 1 mm = 1000 microns

A micrometer is a precision measuring instrument that measures the thickness or diameter of objects with high accuracy.

• Micrometers work on the principle of screw gauge.

• The spindle moves along the screw when rotated, and the thimble measures the distance traveled.

• The accuracy of a micrometer is typically within 0.001 mm.

• Micrometers are commonly used in manufacturing and engineering for quality control purposes.

• There are different types of micrometers, including outside microme...read more

GTTC stands for Geometric Tolerance and Tolerance Calculation.

• GTTC is a system used to specify and control the allowable variation in a part's geometry and dimensions.

• It includes symbols and terms used to communicate the desired tolerances to manufacturers and inspectors.

• Examples of GTTC symbols include concentricity, perpendicularity, and position.

• GTTC calculations involve determining the maximum allowable deviation from the specified dimensions and tolerances.

• Inspectors use...read more

Types of gears commonly used in gear boxes include spur gears, helical gears, bevel gears, and worm gears.

• Spur gears have straight teeth and are the simplest type of gear used in gear boxes.

• Helical gears have angled teeth for smoother and quieter operation.

• Bevel gears are used to change the direction of rotation.

• Worm gears are used for high reduction ratios and are self-locking.

• Other types of gears used in gear boxes include planetary gears, rack and pinion gears, and interna...read more
