Scale of Chords

Download the Manas Patnaik app now: cwcll.on-app.i... Hi guys...
To begin let me tell you that a scale of chords may be used to set or read an angle in the absence of a protractor. To draw an angle, compasses describe an arc from origin with a radius taken from the 60 mark. The required angle is copied from the scale by the compasses, and an arc of this radius drawn from the sixty mark so it intersects the first arc. The line drawn from this point to the origin will be at the target angle.

*How to make 90°+ angles by the help of Scale of chord ?*

[@rahulgocher8724]

Thanku So Much for this wonderful video om engineering graphics 👍😊

[@virajamin4499]

You're life saver.. Thank you so much 👏👏👏😊😊

23. Construct a scale of chords showing 5 degrees divisions and with its aid set-off angles
of 25 degrees , 40 degrees 55° and 130 degrees

[@adityush007]

You're a life saver !!

[@shivanipal8482]

construct a diagonal scale to show metre decimeter and centimetre when 1 metre is represented by 2.5 cm and long enough to measure up to 6 m also find RF show a distance of 2.55 m, 3.34 m, 4.44 m

[@shivanipal8482]

construct a plain scale to show metre and decimeter when one metre is represented by 2.5 cm and long enough to measure up to 6 m also find rf show a distance of 3.5 metre

[@sakshivyas3542]

Sir what we have to do for angles greater than 90 ?

[@deepakpunawat4941]

Wow sir man gaye apko maza aa gaya ,jo doubt tha clear ho gaya thanku very much sir .....I also subscribe your channel.for important video..thanku sir apne hamre marks katne se bacha liye 👍👍👍....thanku sir.....

[@thomasdoherty7840]

A very good instructional video! and also a super back to basics way of working out Angles for Roof Carpentry without any calculators or tables!

[@RishikavsAnnie]

Thank you so much for this helpful video, Sir !
What I had thought of doing was this :
Divide the base line AD (D is the point where the 90° arc cuts AB when extended) into 9 parts and then taking each part (0-1, 0-2, ..., 0-9) as radius, draw an arc starting at AD(the line) and ending at AC(the arc) .
My logic was that when you look at the line below AD having perpendiculars dropped from all the arcs, all the rectangular parts seem to be equal, so it should work out in the opposite direction (starting with the rectangles and then moving onto the arcs) also.
I was thinking that this would also divide my quadrant ABCA into 9 equal parts, but it doesn't seem to work .
Why is this so ?

[@ManasPatnaikofficial]

Rishika... You gave written a long message.....
Anyway I am sure that the method I explained is clear.......
I have got to watch the video again to understand what I had I explained.
And frankly speaking, even I have forgot the method.

[@RishikavsAnnie]

@@ManasPatnaikofficial No Sir, you don't need to watch the video again, because my idea is different from what you taught .
In short, my idea was to divide AB into equal parts and then produce angles by taking those parts as radii, which didn't work .
But thank you so much !

[@rohanzade7434]

I think what u say is also correct Rishika...only thing u need to careful about is finding point B which will be 6th point from point A ( which we come to know after seeing sirs final diagram). So in my opinion it can be done the way u said.

[@princeatsrim3159]

It was very helpful

[@anandprakashsingh9147]

Thank you soo much,
Me and my friends were just waiting for this video.

[@shubham1999]

Can we divide the three parts of 30° by hit and trial method ?

[@victorbasil1006]

Nice I like this

[@tmr-stinylovelyworld_345]

Sir,do we need to draw the raw diagram in the main diagram while trisecting the arc as you have shown in the right side in large.And the 2nd qs is if there is given to measure a particular angle,then all the times do we need to draw the scale of chords?

[@syferdtthehacker130]

Can you draw let's 38degrees using that scale of chords

[@tirthankarmahata7816]

Sir your engg. drawing video is very helpfull to us and those engineer who want to learn engg. drawing very clearly...
Sir, Which Software you use for engg. drawing???

[@ManasPatnaikofficial]

Hi Tirthankar
I am sure that these videos are helping u learn...
Keep watching and do let your friends know about this channel so that they can also benefit.......
And i make videos on powerpoint and autocad simultaneously....

[@tirthankarmahata7816]

thank u sir...

Super bro.... Got some good knowledge from this video

[@dasarirajani2420]

Sir ur classes are amazing, I dont even know about this ..but when i saw u r total videos i got a confidence, thank u so much sir

[@Stayweird133]

Tq sir for this interesting vidio.. ✨

how do we find an angle more than 90 degrees?

[@durgeshmark7087]

How we measure more than 90 degrees

[@ajaycarpenter6483]

Subtract that angle by 180° and Mark that angle from opposite side of the last axis

[@sserembaabdulsalaam7125]

Thanks sir . We also need comparative scale

Thanks sir, I enjoyed your class.

[@tahaali_9]

Sir please upload the video about the projection of hexagonal plane inclined to both planes HP and VP. It may inclined at 70 degree

[@gadogarmast]

Please upload with examples

[@the_wanderering_stranger]

another method is to simply divide the AB line into 9 parts (the same way it is done in plain scale). And then cutting arcs equal to the length of the subdivisions (that we get on the line AB) onto the AC arc . And boom we fet the least count as 10 degrees. Way simpler.
