Best ResponseYou've already chosen the best response.0I am stuck with the circle with unknown radius notice that's my first drawing

Best ResponseYou've already chosen the best response.3R1 = 70 + 25 ( the circle with R1 and circle with 25 has the same tangent when they meet)

Best ResponseYou've already chosen the best response.3\((R_2+R_1)^2 = (R_2+30)^2 + 120^2 \) can you guess how i got that?

Best ResponseYou've already chosen the best response.0Isn't this part an arc ?

BAdhi

Best ResponseYou've already chosen the best response.3ok the arc is an part of a circle. ill use arc then when two arcs with different radii meet together, for them to have a smooth connection, the tangents of the each arc has to be same. Sorry i have circled it little bit to the left. refer the below diagram

Best ResponseYou've already chosen the best response.0I know , he 's right, but I can't understand him

Best ResponseYou've already chosen the best response.1The curve has only one straight line, so all the places where the curve changes direction must be where the radii "line up"

Best ResponseYou've already chosen the best response.0from Pythagorean Theorem

Best ResponseYou've already chosen the best response.0That's how you got (R_2 + R_1)^2 = (120)^2 + ( R_2 + 30 )^2

Best ResponseYou've already chosen the best response.0I never thought we'd use Pythagorean in engineering drawing ,

phi

Best ResponseYou've already chosen the best response.3Is this CAD or hand drawing?

TrojanPoem

Best ResponseYou've already chosen the best response.0@BAdhi Unfortunately, hand drawing, the professor said "You all should master hand drawing before moving to Auto CAD."

Best ResponseYou've already chosen the best response.0Thanks guys, SOLVED. Should I write down the figure the steps of how I got R2 ?

phi

Best ResponseYou've already chosen the best response.3Hand drawing is fun.. of course after a little bit of practice.. its kinda become an art ;)

Best ResponseYou've already chosen the best response.0@BAdhi , Do you suggest any improvements to the drawing ? I am stuck a bit in analyzing some drawings to redraw them, is there any tutorials regarding this concept on the internet?

BAdhi

Best ResponseYou've already chosen the best response.3well for starter, never redraw a path that is drawn using a tool again with use of the free hand. I see that youve done that for curves

BAdhi

Best ResponseYou've already chosen the best response.3well sorry I dont have any material in the internet that i know of :(

Best ResponseYou've already chosen the best response.0@BAdhi , I didn't think you will notice xD, I was trying to highlight the main lines , by using heavy lines.

BAdhi

Best ResponseYou've already chosen the best response.3thats another point.. all the lines should be with the same intensity :P. so make sure if you cannot make the curves darker, make the straight lines and others a bit lighter using correct type of pencil (HB, 2B etc.. ) can help on that too
