- 2. Measuring devices • Measuringtools are essential accessories needed to measure physical quantities. In fields such as physics, quality assurance, and engineering, measurement is the activity of obtaining and comparing quantities of particular objects. • The measurement gives a number related to the item under study and the referenced unit of measurement. • One minor error in measurement ruins the whole project. To avoid such errors, you need to be well versed in the different types of measuring tools and their functions.
- 3. Why math isimportant in trades? • Professional craftsmen know the importance of mathematics in trades, since it is used for calculating the connections for metal frames and how to make wooden joints and finding precise angles. craftsmen who are good at math can work on precise, complicated projects. • Math skills allow craftsmen to complete more projects and increase their productivity. Good mathematical skill also allows them to prevent mistakes and inaccuracies that would otherwise ruin their project.
- 4. Torpedo Level • Atorpedo level is a type of spirit level that is an essential tool for any professional working in tight spaces. The body of the level is made of either metal or plastic and contains two or three tube vials. These tubes, or vials, contain yellowish-green additives and are used to determine the surface level.
- 5. vernier calliper • Isa measuring device that consists of a main scale with a fixed jaw and a sliding jaw with an attached vernier.
- 7. Framing Square • Aframing square, also known as a steel square or a carpenter square. Despite its name, the tool is in most cases actually shaped like an L instead of a square, though it is used in many framing projects — from framing structure for buildings. The tool’s main advantage is its ability to identify clean and even angles. It’s usually made of aluminum or other metal and has a long arm that forms a right angle with a shorter arm. The longer arm is typically used to measure right angles.
- 8. Try square • Atry square or try-square is a tool used for marking and checking 90° angles on pieces of metal
- 9. Adjustable Quick Square •The square's adjustable arm ensures precise measurements. Multi-purpose, adjustable design can be used as a saw guide, bevel or protractor.
- 10. Combination Square • Acombination square is a multi-purpose measuring and marking tool used in metalworking. It is composed of a rule and one or more interchangeable heads that can be attached to the rule.
- 11. Measuring tape • Atape measure or measuring tape is a flexible ruler used to measure length or distance. It consists metal strip with linear measurement markings. It is a common measuring tool.

- 13. Pressure gauges (Oxygen/Acetylene) •pressure gauge, instrument for measuring the condition of a fluid (liquid or gas) that is specified by the force that the fluid would exert, when at rest, on a unit area, such as pounds per square inch (PSI) or newton per square centimeter. • https://www.youtube.com/watch?v=q3rApN-b5dw
- 15. Thermometer • Non-contact thermometers,also known as infrared (IR) thermometers, obtain a temperature measurement from a distance. Fast, simple and affordable, an infrared welding thermometer is a great way to get hassle-free temperature readings. • https://www.youtube.com/watch?v=aOgumTfhOss
- 17. Multimeter • an instrumentdesigned to measure electric current, voltage, and usually resistance, typically over several ranges of value.
- 18. Refrigeration manometer • Thiskind of gauge, also known as Freon manometer, is used to measure pressure in freezing and air conditioning in cold rooms, also this instrument used to measure gas pressures.
