Equilibrium and Elasticity

Proof

Proof First, we consider the individual elements of the body.Shows an extended body, of mass M, and one of its elements, of mass m.. A gravitational force F.i acts on each such element and is equal.The subscript on  means  is the gravitational acceleration at the location of the element (it can be different for other elements). Next, we …

Equilibrium

Equilibrium Consider these objects: (I) a book resting on a table. (2) a hockey puck sliding across a friction less surface with constant velocity. (3) the rotating blades of a ceiling fan. and (4) the wheel of a bicycle that is traveling along a straight path at constant speed. For each of these four objects: 1. The linear …
