thank you so much sir good explanation. I'm watching this video before 1 night of final exam and I'm able to calculate this polygon example bcz now my doubt is clear thank you thank you so much sir
Sir thank you sooo much for making us easy topics and your explanation and methods are understandable. I got passed in DOM subject jan/feb 2023 . You helped a lot thanks sir
what is sad about this, my lecturer is too useless to help me, that i have to resort to a YT video where i understand nothing what is being said, but i understand fully on how to solve this , just by following the steps and paying attention to what he is doing on the video, thank you soo much

three masses 8kg, 12kg and 15kg are attached radial distance of 80mm, 100mm and 60mm respectively on a disc are in complete balance.determine the angular positions of the masses of 12kg and 15 kg respectively to the 8kg mass. Ye question kisi RUclips me nhi mil rha sir
So sir when they don't tell us the spacing between the masses should we assume any distance ,or let's say they tell us that A to B = C to D and B to C is twise A to B
We suggest to go for graphical only, as it will not consume more time in examination..

A shaft carries five masses A, B, C, D and E which revolve at the same radius in planes which are equidistant from one another. The magnitude of the masses in planes A, C and D are 50 kg, 40 kg and 80 kg respectively. The angle between A and C is 90° and that between C and D is 135°. Determine the magnitude of the masses in planes B and E and their positions to put the shaft in complete rotating balance. Please solve this question for me

Yea.. with smaller scale you will not get a clear figure. Angle measurements will also be difficult. Go for some higher scales as per highest value of the quantity, to get better visualisation of your figure. Also, better figure makes checking of supervisor easy, hence giving more marks. Tip - Better the presentation of your work, more will be marks. Thanks, Team EL
Good question Roshan Patil; You can also draw the arc below the horizontal couple, and this is absolutely correct. If you will draw the arc below the horizontal couple then you will get different space diagram, couple polygon as well as different force polygon. You will get all these diagrams like a mirror image.(means Jo mass upar hai wo niche aa jayega and Jo mass niche hai wo upar jayega) So finally angles will also get changed. You will get ∆C=290° and ∆D=145° when measured anticlockwise from mass B. And this ans is also correct.
ten masses of 10kg 15kg 20kg attached at radial distance of 80mm 90mm 50mm respectively to a disk on shaft are in complete balance detrmine anguler position of masses of 15 kg and 20kg relative to the10kg mass sir please solve this
Did you mean protractor? If you want to draw using protractor, then yes you can directly draw the force at given angles by measuring it using protractor. But we suggest you to use space diagram to draw the Force using a roller scale, it will be easy and it will take less time in examination also. Hope your Doubt is cleared. If you have any query, feel free to comment us Thank you
Yes it is possible to solve using analytical method, but We suggest you to prefer graphical method for these types of sums as it reduces the calculation work and it is short compared to analytical method. There can be some mistakes in calculation on calculator because of longer equations... So comparatively you will get correct answer in short time by doing graphical method only.
