QUARTER 4 GRADE 7 TLE DIFFERENT HAND TOOLS AND EQUIPMENT USED IN TECHNICAL DRAFTING

[Music] welcome grade 7 students today is another fun and exciting day to learn more about technical drafting i am mr bellan b santos your tle teacher from francisco p felix memorial national high school make sure to like share subscribe and hit that notification bell to get updates on our latest videos together let us master competencies while enjoying the comforts of our home for today's lesson we will focus on the different hand tools and equipment used in technical drafting with the following objectives first this hand tools and equipment based on the job requirements second identify appropriate hand tools and equipment for proper use and lastly classify hand tools and equipment according to their function before we start our lesson let us first play a game directions choose the picture that shows the right set of rules used in the given specialization which set of hand rules is used in electronics is it a or b good job it's letter a which set of hand tools is used in dress making very good it's letter b which set of hand tools is used in carpentry great job it's letter b which set of hand tools is used in cookery is it a or b very good it's letter a [Music] which set of hand tools is used in automotive awesome it's letter b great job students now what is a hand tool a hand tool is an instrument for an equipment that you hold in your hands to do a specific task for example a computer technician uses screwdriver to assemble a computer and a carpenter uses hammer to hit the nails into a piece of wood the tools that we use in drafting could be categorized into two groups the drawing tools and the measuring tools [Music] under the drawing tools are throwing paper a paper that is specially prepared to use in drafting there are different varieties of throwing paper but also paper is commonly used and bond paper is also recommended masking tape is used for fastening the drawing on the throwing table or drawing board it is preferable than the other types of tape because it doesn't damage the board and it will not damage the paper if it's removed by pulling it off pencil sharpener pencils should always be sharpened whenever they show signs of belgians various types and design of sharpeners are available in different stores eraser this is used to clean the dirt off the drawing did you know that there are different types of eraser a soft eraser is advantageous in removing smudges and pencil marks whereas a hard eraser is useful for making changes and correcting errors in the drawing throwing pencil this is one of the most important tools in drawing pencils come in various grates the creative pencil depends on the quality of the paper to be used here are different types of growing pencils and their uses the first ones are hard pencils these are used where extreme accuracy is required especially working on graphs diagrams and shorts the next one are medium pencils these are used for general purpose work in drawing and lastly soft pencils these are too soft to be used in mechanical drafting but are very useful for different kinds of artworks [Music] the next hand tools will fall under measuring tools these are the tools used to produce a quality and accurate drawing or design triangular scale a tool generally used when producing a drawing in an enlarged or reduced for some regular proportions its main function is to reproduce the measurements of an object in full size reduced size and enlarged size p-square a drawing instrument used when making horizontal lines it is also used for guiding triangles when drawing vertical lines it is made up of wood plastic or the combination of both there are different types of square the fixed head its head is fastened to the bait and is used for ordinary work the movable head or adjustable head it has one fix and one adjustable head and use only four occasional brewing the detachable head or removable head it is designed for easy transport the blade could also be used separately as a straight edge ruler triangles it is a three-sided ruler which typically has two equal sides meeting at 90 degrees angle and do a third side at 45 30 including 60 degree angles commonly used triangles are 30 degrees by 60 degrees and 45 degrees by 45 degrees compacts this drawing instrument is used when drawing arcs and circles it is used in a similar way to a divider it is composed of one with a pen leg and the needle point leg being held together with the handle divider it is used when transferring measurements dividing lines and arcs into the desired number of equal parts it can easily transfer accurate measurements by adjusting the divider points and protractor a semi-circular instrument divided into 180 equal parts each of which is called degree it is used to determine gradations of the degrees when measuring arcs angles and circles aside from the common hand rules set of equipments are also used especially in performing much harder tasks the first one is a drawing board the drawing board is a large flat board on which you attach a drawing sheet to make a drawing a drawing board can be the surface of a drafting table or a separate board that is placed on the top of the desk or a table computer set computer is used for computer-aided drafting or cad it means designing using the computer instead of the classical tools like pencil ink rulers and papers to create drawings and to produce a more realistic design [Music] the drafting machine a drafting instrument consisting of link parts that perform the functions of a t-square triangle linear scale and protractor [Music] and lastly a blueprint machine it is a machine that develops and exposes a blueprint paper a blueprint is a reproduction of a technical drawing or engineering drawing using a contact print process on light sensitive sheets and now to test your understanding on the uses of the different hand tools and equipment let us try to answer this quiz game identify what tool or equipment is introduced in each given statement choose the letter of the correct answer number one it is a type of paper specially made for drafting letter a drawing paper letter b bond paper letter c pad paper or letter d graphic paper very good it's letter a drawing paper number two this drawing instrument is used when drawing arcs and circles is it letter a t square letter b protractor letter c divider or letter d compacts very good it's letter d compacts number 3 this tool is used to clean the dirt off the drawing and make changes and corrections is it letter a sharpener is it letter b eraser or letter c pencil or letter d divider good job it's letter b eraser number four it is a large flat board on which you attach a drawing sheet to make a drawing letter a computer set letter b dropping table letter c blueprint machine or letter d drafting machine it's letter b drafting table very good [Music] number five a tool used to determine graduations of degrees when measuring arcs angles and circles letter a t square letter b protractor letter c divider or letter d complex great job it's letter b protractor very good you guys are doing a great job now let's see if we can classify the different tools based on their categories drag and drop each tool to its corresponding column [Music] [Music] [Music] oh [Music] awesome learners now do you know any other hand tools or equipment using technical drafting if you do feel free to use the comment section below and that ends our lesson for today see you next time for more fun and exciting video lessons again this is miss jebel and v santos your tle teacher from francisco p felix memorial national high school thank you so much for watching [Music] goodbye [Music] you
