do not force the gauge or allow it to get stuck in the gap as that means that the gap is a bit too small. ### Using the vernier calipers and micrometer screw gauge - The precision of length measurements may be increased by using a device that uses a sliding vernier scale. - Two such instruments that are based on a vernier scale which you will use in the laboratory to measure lengths of objects are the vernier callipers and the micrometer screw gauge. - These instruments have a main scale (in millimetres) and a sliding or rotating vernier scale. - In figure 1 below, the vernier scale (below) is divided into 10 equal divisions and thus the least count of the instrument is 0.1 mm. - Both the main scale and the vernier scale readings are taken into account while making a measurement. - The main scale reading is the first reading on the main scale immediately to the left of the zero of the vernier scale (3 mm), while the vernier scale reading is the mark on the vernier scale which exactly coincides with a mark on the main scale (0.7 mm). - The reading is therefore 3.7 mm. - A drawing of a scale labelled with "3.0 mm" and "3.7 mm". - Below the drawing: "Figure 1: The reading here is 3.7 mm." - A drawing of a scale labels with "15.0 mm" and "15.8 mm". - Below the drawing: ` Figure 1 : The reading here is 15.8 mm.` - • Caliper: Caliper is a measuring tool used for measuring the distance between two symmetrically opposing sides. - It can be like a compass with inward or outward-facing points and the tips can be adjusted to fit across the points to be measured. - When the caliper is removed, the distance between the tips is measuring using a ruler. - There are different varieties of calipers like as follows: - A picture of an inside caliper. - A picture of a outside caliper. - • Inside calipers: To measure the internal size of an object. - • Outside calipers: To measure the external size of the object. - • Vernier calipers: Can be used to measure both the inside and outside of an object. - Digital calipers: It has an electronic digital display, shoeing the measurements. - Calipers are widely used in the metalworking field of mechanical engineering, and in woodworking and wood turning. - • Tapes: A Tape rule, also known as tape, is a concave, spring-steel blade ranging from 1/4" to 1" wide and from from 6 to about 300 feet in length, coiled inside a carrying case. - Metric tape rules come in comparable widths and lengths up to 10 meters. - Because the tape rule is flexible, it provides an easy means for accurately measuring curved surfaces. - The concave cross section allows it to be extended unsupported. - Contained in the housing of some models are spring mechanisms that release or retract the tape. - Many tapes have markings for laying out studs on 16" centers or other specialized markings. - Since blades receive hard wear, replacement blades or complete drop-in cartridge assemblies are offered to fit all sizes of tape rules. - In addition to pocket or power tapes, 25', 50' and 100' flat steel tapes are available, as are metric tapes up to 50 meters. - Longer tapes are contained in durable cases and rewound by a crank on the side of the case. - Continuous filament fiberglass and woven tapes also are available in sizes up to 300'. - The most common types of steel tapes have a hook at one end to let one person take all the readings. - • Levels: Levels are common measuring tools available in many sizes and shapes. - The most popular size of level is the 24" long level. - They are made of wood, plastic, aluminum etc. - There are some levels with fixed vials, while some others have adjustable vials. - The basic purpose of levels is to make sure that your work is true horizontal (level) or true vertical (plumb). - In such a case the trick is to use the longest level possible. - Inside the vial of the level, there is a fluid with an air bubble. - When the bubble is centered between the two indicator lines the conclusion is that the surface is level. - The lengths of the level can range to 6 feet. - The torpedo level is 8" or 9" in length. - Here there are vials that read level, plumb and 45 degrees. - These vials are used for small pieces of work. ## QUALIFICATION : DRIVING NC II ## UNIT OF COMPETENCY : Drive light vehicle ## MODULE TITLE : Driving light vehicle ## LEARNING OUTCOME NO. 3.
