Hi
I got a question regarding conservation of mechanical energy. The mechanical energy of a system is conserved, as long as there are no transfer of energy (like heat, work, mechanical waves etc.), right? So, why is the mechanical energy in the system of the pivoting rod and the earth, as shown in the picture below conserved? Isn't there are a force acting from the pivot point, doing work?
I wasn't sure whether I should post it here, or in the homework section, but I figured since it was a general problem relating to mechanics, it was better to post it here.
Thanks in advance
