Hello mr , i just want to thank you because i love the Mechanical engineering and you are awesome in this section , thank you and keep going .
I just wanna say, i watched a couple of concepts and you are so easy to understand, great videos.
Happy to hear that!
To calculate the total force required to move the rail, do we have to add this force with Rolling friction Force on each wheel?
Then answer is yes. But that is why trains are so efficient moving freight. The rolling friction is very low since there is so little deformation of the steel wheels.
Why didn't we account for the moment caused by W?
W acts directly over the axle and doesn't cause a moment.
