Free Caliper MCQ Objective Questions and Answers

Question 1

The caliper known as is used to determine the center of round bars.

Accepted Answer

Jenny Calipers

Answer

Jenny calipers, also known as oddleg or hermaphrodite calipers, have one leg pointed and the other bent. This unique design allows them to be used for scribing lines parallel to an edge or, more specifically, for accurately locating the center of round or square bars by scribing arcs from the circumference. Their distinct shape makes them ideal for this specific task.

Question 2

Which of the following kinds of calipers is used to draw parallel lines to borders on both the inside and outside?

Accepted Answer

Jenny caliper

Answer

Jenny calipers, also known as oddleg or hermaphrodite calipers, are specifically designed for layout work. They feature one fixed leg and one adjustable leg with a pointed end, allowing them to accurately scribe lines parallel to an edge. This capability applies to both inside and outside borders, making them ideal for marking out workpieces.

Question 3

Vernier calipers' lowest count is determined by the following:

Accepted Answer

Difference between a main scale division and a Vernier scale division

Answer

The least count (LC) of a Vernier caliper is defined as the smallest measurement that can be accurately read by the instrument. It is fundamentally calculated as the difference between the value of one main scale division (MSD) and the value of one Vernier scale division (VSD). This difference represents the smallest discernible change in measurement the caliper can detect.

Question 4

Calipers that come with the heel or regular leg are referred to as:

Accepted Answer

Hermaphrodite calipers

Answer

Hermaphrodite calipers, also known as Jenny calipers or oddleg calipers, are characterized by their unique leg configuration. They have one leg that is straight and pointed (the regular leg) and the other leg that is bent or has a heel. This design makes them suitable for scribing lines parallel to an edge and for finding the center of round stock.

Question 5

The metric system's minimum vernier caliper count is

Accepted Answer

0.02 mm

Answer

The 'minimum count' or least count of a measuring instrument indicates its precision. For a standard metric Vernier caliper, the most common and widely accepted least count is 0.02 mm. This precision is achieved through the specific graduation of its main and Vernier scales, allowing for fine measurements.
