WHAT ARE THEY ? tangency is. . . A PROCEDURE WHICH ALLOWS YOU TO INCORPORATE CURVES ACCURATELY INTO YOUR 2 D TECHNICAL DRAWINGS. the principles are. . . THE RULES WHICH DICTATE HOW TANGENCY IS DONE graphic communication @ boclair academy

HOW DO YOU DO IT ? There are four common problems you have to learn to deal with. They are. . . tangent at a right angle tangent at an acute angle graphic communication @ boclair academy tangent at an obtuse angle tangent with two curves

HOW DO YOU DO IT ? tangent at a right angle draw complete set measure where the two compass they faint 30 mm the tangent intersect, lines along atdraw 30 mm parallel each and the to of is faintly from draw each two line, lines atwith athis right faint horizontal scribe the two and the centre vertical arc as of the shown lines arc angle line tothe establish out atoriginal a these right the corner angle right angle graphic communication @ boclair academy

HOW DO YOU DO IT ? tangent at an acute angle draw complete set measure where from faintly the two compass each they faint 30 mm the draw line, tangent intersect, lines two along atdraw 30 mm lines parallel with each athis at faint and the an to of is scribe line the out two the centre at other original arc aacute these right as of two the shown angle lines arc right angle graphic communication @ boclair academy

HOW DO YOU DO IT ? tangent at an obtuse angle draw complete set measure where from faintly the two compass each they faint 30 mm the draw line, tangent intersect, lines two along atdraw 30 mm lines parallel with each athis at faint and the an to of is scribe line the out two the centre at other original arc obtuse a these right as of two the shown angle lines arc right angle graphic communication @ boclair academy

HOW DO YOU DO IT ? tangent between two curves scribe now faintly draw from you two indraw where can the arcstwo line in 60 mm they the circles, thecentres intersect, required from each the of scribecentres an with arc a arc 40 mm radius of two the in heavily circles radius 20 mm R 40 R 20 graphic communication @ boclair academy
