Answer to Question #4452 in Mechanics | Relativity for farfia
a solid sphere,spherical shell, solid cylinder and a cylindrical shell all have the mass m and radius R. if they are all released from rest at the same elevation and roll without slipping, which reaches the bottom of an inclined plane first?
Solid sphere will reach the bottom of an inclined plane first, cause it has the smallest moment of inertia: solid sphere:& I = 2mR^2/5 spherical shell: I = 2mR^2/3 solid cylinder:& I =& mR^2/2 cylindrical shell: I =& mR^2
I'm extremely satisfied with your work. Excellent quality. Always.
Just have a question. Do you also provide help in understanding a concept? Not an assignment but for my learning. If certain concepts in the book are not clear, can you provide a simplified explanation of it using math that's understandable? You can charge the equivalent of an assignment.
Some things in the chapter attachments I sent you are not clear. They do not have much solved examples either.
Thanks a lot,
