sir for couple polygon if a is negative then u take it in left direction but c is positive then for c also u went left didnt get that one. same in force polygon for mq u went up and for md u went down since both are positive why so?
Ty sir.bt in book & i saw the last year pune university paper the did not mention how to solve numrical by graphically or Anylatical so how we'll know in exam ?
Yes it can be solved by analytical method as well as graphical method. But we suggest you to use graphical method only bcz graphical method is short and comparatively easy. It will save time and reduced calculation errors. So if nothing is mentioned in question, then go for graphical method.

Hi , great video for understanding as well as solving the problem... I have a thought is there any other method to find the angular position of mass mq
Explanation was really good but in the question mass q is in between CD and mass p is in between AB so angle of mass Q will be 280 and Mass P will be same

Yes you can. But in some cases if the polygon become very small, then you should take larger scale, so that the polygon will be bigger and more accurate.
Sir how to do balancing in which there are given three masses out of which first two masses are in between the bearings and the other one is outside the bearing??
Thanks brother to tell me that how to set the scale. But i have one problem still in the force polygon diagram , that i get confuse when we draw the line for the mp mass i don't know that at which angle the line should be drawn.

Sir diagram me agr find out kiya hua distance 1mm or 2mm vary raha toh marks kat te hai kya Jaise aapka OD 91 mm aaya hai or mere 89 aaya tha And angle me vary kitana allowed hota hai
Sir , after finishing couple polygon why did u mark resultant line of mQ in the second quadrant only why not in fourth quad of space diagram ?? Same with mP after finishing the force polygon u drew it in third quad why not in first quad of the space diagram??
Start from the force polygon instead if you have all values in the column of force polygon....and then go for couple polygon. You will get good idea from this numerical: th-cam.com/video/NLwdImxGtjM/w-d-xo.html Hope this helps you

I have a doubt that question m tha ki jo mass p h vo mass a and mass b k between h and mass q h vo mass c and d ko to fir yeh space diagram m opposite ku ho gya iska koi reason?
See the diagram of position of planes. In that you will find mass P is between A & B. But ye Linear distance hai. And angular distance 105° hai so it will be between B & C in space diagram
Take larger scale to draw the couple polygon. Take scales like 0.09 kgm²= 5cm (means 1cm =0.09/5=0.018 kgm²) i.e 1cm = 0.018 kgm². So you will get accurate diagram...
If the value of force or couple is +ve then You have to draw the vector IN THE SAME DIRECTION of masses drawn in space diagram. For eg mass mb has +ve couple, so you have to draw vector in same direction of mass mb (watch at 16:40) and if the value of force or couple is -ve then You have to draw the vector IN THE OPPOSITE DIRECTION of masses drawn in space diagram. For eg mass ma has -ve couple, so you have to draw vector in opposite direction of mass ma (watch at 15:55)
Bruh different explanation in video and comments😐.. In video you just told we draw towards left coz the couple Id negative and you have a different explanation here..😑

Best MADOM teacher ....💯
17:09 why you take it in (-ve) direction ?
Direction depends on space diagram mass angle will be the direction
@@RNs_CREATION then you must take b also downwards bro
sir for couple polygon
if a is negative then u take it in left direction but c is positive then for c also u went left
didnt get that one.
same in force polygon
for mq u went up and for md u went down since both are positive
why so?
bro we have consider sign for only first ray the next ray are taken according to their angles

Distance from reference p and q is 0.475m and you have taken same midway of A and B so not 175 it would be 150

And angle me vary kitana allowed hota hai
Sir , after finishing couple polygon why did u mark resultant line of mQ in the second quadrant only why not in fourth quad of space diagram
?? Same with mP after finishing the force polygon u drew it in third quad why not in first quad of the space diagram??
Usko bhi nai jaantha baai🤣
What if there is no non zero value in couple polygon to draw couple po..
Start from the force polygon instead if you have all values in the column of force polygon....and then go for couple polygon.

Great video sir 👍
But Mp and Mq ke angle galat measure kiye h Mp Ma aur Mb ke bich me aayega
At 3:00 i loved the vedio
In couple polygon scale the minimum non zero value is -3.97....but u have taken 3.25 as scale
As I solved the couple polygon on the graph paper whereas its difficult to put the roller parallel for checking the angle....

Nice explained
Thank you Abhishek.

Measured clockwise from mass in plane A. Numerical me kese Hota he
B'c' is drawn left side instead of right even though value is +ve like oa' where its negative value
That's why I was also confused...
I have a doubt that question m tha ki jo mass p h vo mass a and mass b k between h and mass q h vo mass c and d ko to fir yeh space diagram m opposite ku ho gya iska koi reason?
Space diagram me mass P and Q kaha par draw karna hai wo couple polygon and force polygon ke resultant pe depend karta hai.
@@EducationLessons Thanku for ur kind help😊👍
See the diagram of position of planes. In that you will find mass P is between A & B.
But ye Linear distance hai.
And angular distance 105° hai so it will be between B & C in space diagram
Sir pls explain in English 😊 it's really cool👍
Sure Kisor. We will provide videos in English also as early as possible ✌

When the couple values comes under 0.09,0.1,0.14 wat will u do
Take larger scale to draw the couple polygon.

So you will get accurate diagram...
@@EducationLessons tq keep doing
How to decide the directions of vectors??
You drew oa towards left because it was negative what about others..?
If the value of force or couple is +ve then You have to draw the vector IN THE SAME DIRECTION of masses drawn in space diagram. For eg mass mb has +ve couple, so you have to draw vector in same direction of mass mb (watch at 16:40)
and if the value of force or couple is -ve then You have to draw the vector IN THE OPPOSITE DIRECTION of masses drawn in space diagram. For eg mass ma has -ve couple, so you have to draw vector in opposite direction of mass ma (watch at 15:55)
