Ok thank you! Both ways (conservation of mechanial energy and analytical integral form of work for every dm) give the same result for the velocity as a function of the angle.
This makes me more confident about the correctness of the solution.Still I have not got a 100% thorough understanding of...
Thank you Orodruin! :D I will stick with the second method!
One last question:
In the end does the total Normal force produce any work?
If it does, I cannot use conversation of mechanical energy to find the velocity and I will have to find the total work done in a similar way to the second...
Thank you sir.
No, I have not leaned Lagrangian mechanics yet. This problem is part of a first semester mechanics course.
The second approach then must be right since it is based on the FBD's for every dm.
Could you please comment on the validity of the first approach?
Thank you for your reply.
Hi! I am struggling with this problem the last two days and I cannot decide which solution is correct.
Homework Statement
A cylinder of radius R is fixed horizontally on the floor. A uniform chain of mass M and length L (L<πR/2) is placed on the cylinder in such a way that one end of the...
Hi,
I am 1st year undergrad student at "national technical university of athens" (probably you have never heard of this university :biggrin:) in the department of electrical and computer engineering.
When applying I had a very hard time choosing between electrical and mechanical engineering.(I...
