<h1>BASIC FREEHAND TECHNIQUES OF DRAWING CIRCLES, IRREGULAR SHAPES, ETC.</h1> <p>CONTENT</p> <p>Basic Freehand Techniques of Drawing Circles, Irregular Shapes, etc.</p> <ol> <li>Sketching a Straight Line</li> <li>Sketching a Curve</li> <li>Sketching a Circle</li> <li>Sketching a Square Box</li> <li>Sketching an Irregular Edge</li> </ol> <p> </p> <h2>Techniques of Sketching</h2> <h3>Sketching a Straight Line</h3> <p>A straight line is defined as the shortest distance between two points. We can use freehand to draw a fairly straight line by the following procedures.</p> <ol> <li>Put a dash or dot far enough to the right-hand side of the paper.</li> <li>Start to draw a line from the left-hand side to join the dash or dot with your eyes fixed on the point.</li> </ol> <h3>Sketching a Curve</h3> <p>To draw a curve by freehand, it will be necessary to plot some points not too far from each other at different levels, like this --------- with the points in position attempt to draw curves by joining the dashes or dots.</p> <h3>Sketching a Circle</h3> <p>To draw circles, the easiest way is to draw lines which are equal in diameter to the circle in different directions. Each line must be as faint and straight as possible, each crossing one another at a central point. Now, join the points by little curves from the top of each line. Try to draw other circles by means of joining two large curves having half the size as radius and full size in diameter.</p> <h3>Sketching a Square Box</h3>

Technology is basically a systematic way of doing things or solving problems for the good of mankind. Technology is also a human activity directed at designing and making products like machines, computers, textiles, household devices and others, which make human living comfortable.</p> <p>Technology is the processes (method) and products (materials) that make life easy and stress free. It can also be defined as cultural traditions developed in human communities for developing the physical and biological environment. Technology is also a new knowledge, idea, skill, procedure, or technique for doing or using things which may result into new things being produced. Technological development could be traced in the following areas:</p> <ol> <li>Food</li> <li>Clothing</li> <li>Shelter</li> <li>Communication</li> <li>Transportation, and</li> <li>Manufacturing.</li> </ol> <p> </p> <h2>Technology-related Professions</h2> <p>Technology is in the area of producing things, and providing services or using things in given ways. Such areas of human endeavor include engineering and construction, medicine, pharmacy, agriculture, business and commerce.</p> <p> </p> <h2>Technology Occupations/Careers</h2> <p></p>

They are:</p> <ol> <li>Measuring tools</li> <li>Marking out/setting out tools</li> <li>Work holding tools</li> <li>Boring tools</li> <li>Cutting and paring tools</li> <li>Driving tools.</li> </ol> <h3>The Work Bench</h3> <p>A very vital tool in the wood workshop upon which operations such as sawing, drilling, planning, chiseling and boring are all carried out.</p> <p>Work bench fittings are:</p> <ol> <li><strong>Bench Stop</strong> is a provision made to prevent the work piece from slipping off the top surface of the work bench during planning.</li> <li><strong>Bench Hook</strong> is a device used to hold the job (or work piece) down during sawing or chiseling.</li> <li><strong>Bench Vice</strong> is a device that has a torsion bar for opening the jaws to allow a work piece to be held firmly between them. Usually more than one of this is fixed on the bench.</li> <li><strong>The Well</strong> is an important longitudinal hollow feature at the center of the work bench which serves as storage area for keeping bench tools during the process of work.<img class="size-full wp-image-36641 aligncenter" src="https://classhall.com/wp-content/uploads/2018/06/the-work-bench.jpg" alt="Measuring and marking out tools - Work bench" width="470" height="222" /></li> </ol> <h2>Measuring Tools</h2> <p><strong>Measurement</strong> is the first operation in woodwork.
