Am I the first to observe that this is the best YT channel for understanding Engineering Mechanics and Engineering Drawing? (just an unbiased opinion)
u r a real saviour sir.. i was not good in ed but after listening to ur lecture videos i scored really good and got the correct imagination also. thank u so much sir
right❤
didi ED ya EM
Hy can you answer qsn
1:Determine the position of centroid[3]
2:second moment of area about the vertical centroidal axis[6]
3:Radius of gyration about the vertical centroidal axes[3]
You are my Savior I follow you from Iraq, a student at Shatra University
Very very good technique s and teaching methods
Your a savior Manish ji. I understood exactly what you said from your video. Thank you!
Thank you soon much sir... Helped me a lot.....I think this is one among the best you tube channels for em ...thank u soo much 😆

If we are not given the x and y axis like this question, can we place the axis anywhere along the structure?
Maan I understand this guy better than my professor
My calculus exam is tomorrow. Thank you for this sir!

You are the best teacher
Thank you so much sir , You are our god 🙏 You bless you . (God bless you 😁)
Hi Manas - Would I get the same answer if I would have computed area 1 as the {area of the rectangle - area of the semi circle} ?
sir when do we use 2/3 in calculating x or y coordinate
my question I just saw that on the other video when calc x for semi semi circle you subtract the radius from 4r/3pi and on this one you just used 4r/3pi help me understand sir
Distance has to be taken from the axes and then measurements are done. Think about it and i would suggest you observe both the solutions again. There is a subtle difference.
wow
plz upload more videos on this concept...
Dude may God bless you are really helpful
Thank u .....

Thank you sir for this explaination.
thank you for the video , i was asking for the semicircle y Did u use 4r/3π
Same doubt for me also
excellent explaination
Thanks Qaiser and enjoy the videos
sir i would like to request you to make more videos on numericals based on dynamics
Thsy have already been uploaded. Search it on my channel page.
And more videos will be uploaded in future as well.
thank you sir
Great....
Nice presentation Sir. May I know the software you used during the presentation?
Bro you need to eliminate the hemisphere from rectangle for A1
Nice expalinations
Sir please upload how to take strip while finding centroid of objects??
Thank you sir🎉🎉🎉

Sir can you explain in depth problems very depth problems, i exam questions are asking in depth sir, in this centroid and moment of inertia models sir.....
thank u sir
helped a lot
Why you didn't negative the unshaded areas?
Sir... Please upload on how to draw nut and bolts...
Sir i wanted to know how to calculate that area
I'm learning but also send for me the centroid of circles enclosed together, because I'm having a problem in finding the Iyy and Ixx
Kibet.......Can u please rephrase your question. Be very clear and concise in what u ask

TnQ sir
Sir when you find y2 you take 30+20/3
But when you find y1 you directly take 30/2 not 20+30/2
Why?
Hi therr....
look when you are taking distances you need to consider an axis and here we are taking vertical distances okay or the y cordinates
so you have to take all of these distances with respect to the x axis.
Area 1 happens to be a rectangle and its height is 30 so 30 by 2 will be 15 and this distance directly comes wrt x axis, but Area 2 is a right angle triangle whose height is 20 so 20 by 3 is the value from the base of the triangle
But we want a distance from the x axis that is why I added 30 to it so the distance of the centroid of area 2 from the exactis will be 30 + 20 / 3
Thank you so much sir
Sir u just rock m blessed that I listen you 👉sir can make a video in friction chapter
Checkout the topics from this playlist Rahul.....

@@ManasPatnaikofficial thanks 🙏🙇a lot sir
sir, centroid for semicircle along Y -axis is 0. right?
and along X-axis is (4R/3pie)
how can we take 15 as Y in semicircle.?
Why in x3 you use 4r/3bay I think you must use R which D/2 !!
Excellent
Thanks Chandresh....
Great
Why did you use minus sign for the semi circle
The area of the rectangle should be (bh- pi*r(sqr)/2). I think.
Thank you sir
Someone please calrify that how to take X3 calcualtion
the equation for xi for a semicircle is 4r/3π that is what sir used here
The centre of semi circle ⭕ can it be 15/2=7.5
in this problem for calculating the area of A1 why not 750-(pi*225)/(2) because material whose area is about half of the semicircle has been removed from the area of rectangle
Yes exactly
sir y 20/3 and 25/3 in case of rectangle pls explain
Sir please tell us how to locate the position of the centroid
Sir plz solve some ques on basis of moment of inertia
Good
Sir can you please slove problems on Moment of inertia
Super
Sir tell about the force in a space
What textbook are the questions from?
I don't know how to apply the formula
Make video on
Question Example:-
Two blocks of masses M1 and M2 are connected by a string as shown in Figure 5.
below Assuming the coefficient of friction between block Mị and the horizontal
surface to be u if the system is released from rest, find velocity of the block A
after it has moved a distance of 1 m Assume Ml00kg.and M2-150kg and
u0.20.

sir please upload rolling numerical
Use camtesia studio
Thank you sir❤️❤️
Upload circle questions bro
In 4r÷3pie what is the value of r??
Since the diameter of the circle is same with the height of the rectangle, the diameter is 30. So we get the radius 30÷2=15. 4r÷3π is the centroid formula for semicircles.
What did you study ?
in semicircle r is 30 na
Sir why did you subtracted the A3
Because it is a hole. It has negative mass.
I mean it is not included in the solid.. i hope you understand what im trying to say.
Please sir
X3 Kash nikala sir nahi aaya
Y* is wrong

That is current
Sir semi circil to cut hua hai na
