Our aim is to simplify the analysis. Otherwise there may have all 6 degrees of freedom in most of the cases(microscopic level)
So useful this ...
Thank you...
clearly explained. Thanks Joji !
Thank you sir! 🙏Clearly explained. 🌸
Thank you sir great explanation
Very good explanation
Thank you
In the last portion of presentation,ref various figures ,there in the book , mentioned ,class, forms,restraints ,could not be understood please.
🔥👍
can someone drop all the answers for the exercise at the end of the video please
👍👍👍
How many degrees of freedom does a block going down an inclined plane have in xy plane??
1
@@drjojithomas explain plz??
Hello Sir! can i ask if what is your reference book?
Theory of Machines by S S Rattan Mcgraw hill publication
Thank you so much Sir.
thx
B figure how many degree of freedom??
b)4 degrees of freedom
@@drjojithomas sir suppose radius of cylinder is slightly more than radius of sphere...how many degree of freedom the sphere has??

@@drjojithomas thnk u so much sir...I also feel..there is six degrees of freedom...
@@drjojithomas How? there is no plate so 6 dof
