A video of people on a beach in Cape Lookout with captions describing that a camera was found, which depicts wildlife footage, including a bobcat, deer, fox, and a beaver that felled the tree on which the camera was hung. At the end there is a call to share to find the camera’s owners
Back to our beloved books. They ask for nothing. They fill the room with everything you need. Salvation in their presence.

A block is placed on a horizontal rail, along which it can slide frictionlessly. It is attached to the end of a rigid, massless rod of length R. A mass is attached at the other end. Both objects have weight W. The system is initially stationary, with the mass directly above the block. The mass is given an infinitesimal push, parallel to the rail. Assume the system is designed so that the rod can rotate through a full 360 degrees without interruption. When the rod is horizontal, it carries tension T1​. When the rod is vertical again, with the mass directly below the block, it carries tension T2. (Both these quantities could be negative, which would indicate that the rod is in compression.) What is the value of (T1−T2)/W?
