... Now, let’s do a trick. We will view the whole system from a frame of reference which is moving along with velocity equal to the velocity of the center of mass. Let’s say that a body is moving at 10 m s-1 in the original reference frame, and that the center of mass is moving in the same direction at ...

Since this relation involves t, the Hamiltonian is not the energy. But H is in fact conserved, because there is no t dependence ...

The 2:1 Rule and How to Define Fixed and Floating Bearings
... THE 2:1 RULE AND HOW TO DEFINE FIXED AND FLOATING BEARINGS When using DryLin®, it is important to ensure that all acting forces follow the 2:1 rule. In a nutshell, if either the drive force (Fa) or applied load force (Fs) are a greater distance than twice the bearing length (wx), then a binding or c ...
