Measuring and Marking Tools Quiz

What is the primary purpose of a measuring tool?

• To indicate a point

• To mark a surface

• To measure physical quantities

• To draw lines

Answer explanation

The primary purpose of a measuring tool is to measure physical quantities, such as length, weight, or volume, providing accurate data for various applications. Other options do not capture this essential function.

Which of the following tools is used to measure weight?

• Spirit level

• Voltmeter

• Weighing balance

• Plumb bob

Answer explanation

The weighing balance is specifically designed to measure weight by comparing an object's mass against known weights, making it the correct choice. The other tools serve different purposes.

Which tool consists of two adjustable jaws used for measuring internal and external dimensions?

• Square

• Calipers

• Scriber

• Micrometer

Answer explanation

Calipers are the correct tool as they have two adjustable jaws specifically designed for measuring both internal and external dimensions, unlike squares, scribers, or micrometers which serve different purposes.

Identify the tool shown in the picture that measures voltage in an electrical circuit.

• Ammeter

• Ohmmeter

• Voltmeter

• Multimeter

Answer explanation

A voltmeter is specifically designed to measure voltage in an electrical circuit. An ammeter measures current, an ohmmeter measures resistance, and a multimeter can measure multiple parameters, but the correct tool for voltage is the voltmeter.

Which measuring tool is commonly used for drawing perpendicular lines?

• Steel rule

• Tape measure

• Square

• Punch

Answer explanation

A square is specifically designed to create right angles, making it the ideal tool for drawing perpendicular lines. Other tools like a steel rule or tape measure do not serve this purpose.

What is the main feature of a spirit level shown in the picture ?

• Sharp ends for scribing

• Sealed glass tube with liquid and air bubble

• Curved legs for marking

• Adjustable blade angles

Answer explanation

The main feature of a spirit level is the sealed glass tube containing liquid and an air bubble. This design allows users to determine if a surface is level by observing the position of the bubble relative to the marked lines.

What is the main material used to make steel rules?

• Plastic

• Aluminum

• Stainless steel

• Wood

Answer explanation

Steel rules are primarily made from stainless steel due to its durability, resistance to corrosion, and ability to maintain accuracy in measurements. Other materials like plastic or wood do not provide the same level of precision.

Which tool is used to measure temperature?

• Voltmeter

• Stopwatch

• Thermometer

• Ohmmeter

Answer explanation

A thermometer is specifically designed to measure temperature, making it the correct choice. The other options, like voltmeter and ohmmeter, measure electrical properties, while a stopwatch measures time.

What type of tool is a plummet shown in the picture?

• Time-measuring tool

• Electrical measuring tool

• Weight-measuring tool

• Vertical alignment tool

Answer explanation

A plummet (plumb bob) is used to determine vertical alignment by providing a true vertical reference. It is not a time, electrical, or weight-measuring tool, making 'Vertical alignment tool' the correct choice.

Which tool is used for measuring angles and has an adjustable blade?

• Sliding bevel

• Marking gauge

• Micrometer

• Punch

Answer explanation

The sliding bevel is a tool specifically designed for measuring angles, featuring an adjustable blade that allows for precise angle settings. The other options do not have this capability.
