Question

Which one of the following is NOT a part of a Vernier Caliper

depth measuring blade

beam

ratchet

locking screw

​

Answer 1

Ratchet is not a part of a Vernier Caliper.

• A Vernier caliper is an instrument that is used to measure the outer, inner dimensions, and thickness of steel objects.
• It has a depth measuring blade that goes into holes or steps to take readings.
• A locking screw fixes its position to avoid any error.
• The Beam is also called Bar and is used to read measurements in inches or tenths.

Answer 2

Ratchet is not a part of a Vernier Caliper.

Step-by-step explanation:

Vernier Caliper:

• Vernier calipers are the type of tool for measuring.
• This tool is used to get accurate linear dimensional measurements.  
• Also, this tool helps us to measure the cylinder diameter because its jaws are can be tightened on both the sides to get accurate measurements.
• The Vernier caliper figure is shown below.

Vernier Caliper parts:

It has 7 major parts. These are,

• Locking screw
• Vernier scale
• Main scale (Beam)
• Depth measuring blade
• Thumbscrew
• Lower jaws for outside measurements
• Upper jaws for inside measurements

Here,

• In the given question have the 3 vernier caliper parts. These are beam, depth measuring table and locking screw.

• Hence, the ratchet is not a part of the vernier caliper.
