Engineering Graphics and Design Unit 1 1. A rectangular plot of land area 0.45 hectare, is represented on a map by a similar rectangle of 5 square cm. Calculate R. F. Of the scale of the map. Also draw a scale to read upto single meter from the map. The scale should be long enough to measure upto 400 meters. 2. A car is running at a speed of 50 km/hour. Construct a diagonal scale to show 1 km by 3 cm and to 6 km. Mark also on the scale the distance covered by the car in 5 minutes 28 seconds. 3. An area of 144 sq. Cm on a map represent an area of 36 sq. Km on the field. Find the R.F. of the scale and draw a diagonal scale to show kilometres, hectometres and decametres and to measure upto 10 kilometres. 4. A 3.2 cm long line represents a length of 4 meters. Extend this line to measure length upto 25 meters and show on it units of meter and 5 meters. Show the length of 17 meters on this line. 5. The R.F. of a scale showing miles, furlong and chain 1/50688. Draw a scale to read upto 5 miles and show on it, the length representing 3 mile 5 furlong 3 chains. 6. A room of 1728m3 volume is shown by a cube of 216m3 volume. Find R.F. and construct a plain scale to measure upto 42m. Mark a distance of 22m on the scale. 7. Explain Dimensioning . Give various methods of Dimensioning. 8. Explain briefly about the conventional line types and their usage. 9. Explain Lettering with appropriate examples. 10. A cube of 5cm represents a tank of 8000cubic metre volume. Find the R.F and construct a scale to measure upto 60m and mark a distance of 47m . Indicate R.F of the scale.
