# RGPV Engineering Graphics PYQs

Q1. What are Scale? Classify its different types, also describe how RF is calculated.

Q2. A rectangular plot of land arca 0.45 hectare, is represented on a map by a similar rectangle of 5 sq. cm. Calculate the RF of the map, Also draw a scale to read up to single metre from the map, the scale should be long enough to measure up to 400 metres.

Q3. An inelastic string is unwound to a length of 122 mm from a drum of 30 mm. Draw the locus of free end of the string which is held taut during unwinding.

Q4. The projections a’b’ and ab of a line AB are 65 mm and 50 mm long, respectively. The midpoint of the line is 38 mm in front of VP and 30 mm above HP. End A is 10 mm in front of the VP and nearer to it. End B is nearer to the HP. Draw the projections of the line, find its true length.

Q5. A regular hexagonal lamina 40 mm side has a square hole of 25 mm side centrally cut through it. Draw its projections when it is resting on one of its sides on HP with its surface inclined at 60° to VP and its corner nearest to VP is 24 mm from VP.

Q6. A triangular prism of side of base 30 mm and axis 55 mm long lies on one of its rectangular faces in HP with its axis parallel to VP. Draw its Projection.

Q7. A right regular square pyramid, edge of base 35 mm and height 50 mm, rest on its base on HP with its base edges equally inclined to VP.
