problem 2)(a) With neat sketches, demonstrate how the following are dimensioned: Circles, holes chamfered surfaces, angles, curves.
(b) Draw the following systems of placing dimensions:
(i) Aligned system
(ii) Unidirectional system
problem 3) Construct a diagonal scale to read up to 1/10 of a mm, long enough to read up to 60mm, taking R.F=3/1. Show a distance of 47.8mm on this scale.
problem 4)(a) Sketch projections of the following points:
(i) Point A, 50mm in front of VP and 30mm above HP.
(ii) Point B, 40mm behind VP and 20mm below HP.
(b) A line AB, 35mm long is perpendicular to HP. Its end B is 15mm from HP and 20mm from VP. If the whole line lies in third quadrant, draw its projections. The line is parallel to VP.
