To Determine Volume of an Irregular Lamina Using Screw Gauge Viva Questions

Content Curator

A screw gauge, also known as a micrometer, is a device with a calibrated screw that is widely used for accurate measurement of components.

It is used to measure the dimensions of extremely small objects up to 0.01 mm.
A screw gauge is constructed of a U-shaped metal frame. A hollow cylinder is attached to one side of the frame.
Grooves are cut on the interior surface of the cylinder through which a screw travels.
On the cylinders parallel to the screw axis, a millimeter scale called Pitch Scale is graded.
The main scale that measures the distance traveled by the spindle on each turn (in millimeters) is known as the pitch scale.
The distance traveled by the tip of the screw when turned through one division of the head scale is defined as the least count of the screw gauge.
The least count of a screw gauge is 0.01 mm.

Ques. Of what metal is the screw of the screw gauge made and why?

Ans. Gunmetal is used for making screw gauges. The reason for this is that gun metal experiences the least wear and tear over the course of continuous usage.

Ques. What is a screw gauge?

Ans. A screw gauge, often known as a micrometer, is a measuring instrument consisting of a calibrated screw. It is used to determine the size of small objects. It is a type of meteorological instrument that is used in machining, mechanical engineering, and a variety of other applications.

Ques. Why is a screw gauge so named?

Ans. Wire diameters are represented by specified values known as standard wire gauge (S.W.G). Because it measures these sizes, it is known as a screw gauge.

Ques. What is the zero error of a screw gauge?

Ans. If the zero line on the circular scale does not coincide with zero on the linear scale when the screw on the circular scale is fully tightened or adjusted, the error is known as the screw gauge's zero error.

Ques. What are the reasons for zero error?

Ans. The following are the reasons for zero error

Manufacturing defect
Wear and tear of the screw

Ques. What is the negative zero error of the screw gauge?

Ans. If the zero line on the linear scale coincides with the line below zero on the circular scale when the screw on the circular scale is fully tightened or adjusted. The inaccuracy caused by this is known as negative screw gauge error.

Ques. What are the different types of motion owned by a screw?

Ans. A screw has two types of motion, which are as follows:

The linear motion is possessed by the axis.
The circular motion possessed by the surface

Ques. What do you mean by the least count of a screw gauge?

Ans. The distance traveled by the tip of the screw when turned through one division of the head scale is known as the least count of the screw gauge.

Least count (LC) may be obtained by dividing the screw gauge's pitch by the total number of divisions on the circular scale.

Least Count of Screw Gauge = 1 mm/100 = 0.01 mm

Ques. What is the pitch of a screw gauge?

Ans. The distance traversed by the screw in one complete rotation is known as its pitch.

Ques. How can one avoid backlash errors in a screw gauge?

Ans. Backlash may be prevented by turning the screw in the same direction and putting little lateral pressure on the screw.

Ques. Define 1 metre.

Ans. 1 meter is defined as the distance traveled by light in a vacuum in 1/299792458 seconds.

Ques. What is the least count of Vernier calipers?

Ans. The least count of a Vernier caliper is the division on the main scale divided by the number of divisions on the Vernier scale. As a result, the Vernier caliper's least count is = 0.1 mm.

Ques. What is the difference between mass and weight?

Ans. Weight is the amount of force acting on a mass due to gravity, which is commonly indicated by W, and mass is the quantity of matter contained in a body, which is denoted by M.

Ques. What is Volume?

Ans. A volume is just the amount of space taken up by any three-dimensional solid. A cube, a cuboid, a cone, a cylinder, or a sphere are examples of solids. There is different volume for different shapes.

Ques. What is the SI unit of volume?

Ans. Cubic units are used for measuring a solid's volume. For example, the volume will be represented in cubic meters if the dimensions are specified in meters. The International System of Units (SI) uses this as the reference unit for volume. Cubic meters, cubic feet, cubic inches, etc. are additional volume units.

Ques. What is a Planar Lamina?

Ans. A planar lamina (or plane lamina) is a solid figure that represents a thin, typically homogeneous, flat layer. It also serves as an idealized representation of a planar cross-section of a solid body in integration. Planar laminas can be used to calculate moments of inertia or centers of mass of flat figures, as well as to help with 3D body computations.

Ques. What is an irregular lamina?

Ans. An irregular lamina is an irregular polygon that doesn't have the proper shape and has a negligible thickness in comparison to its length and breadth.

Ques. On what principle does the screw gauge work?

Ans. The screw gauge works on the screw principle. The distance traveled by the tip of a screw as it is turned in a nut is directly proportional to the number of rotations.

Ques. What are measuring tools?

Ans. A measuring tool is a device used to measure the physical dimensions of a body, such as its height, width, length, or temperature.

Ques. Name the five types of screw gauges.

Ans. The five different types of screw gauges are

Tube micrometers
Blade micrometers
Bench micrometers
Ball micrometers
Universal micrometer sets
