X2 T07 06 banked curves
This document discusses motion around a banked curve. It introduces variables like radius (r), speed (v), angle of banking (α), gravitational force (mg), and normal force (N). It derives equations relating the horizontal and vertical forces to these variables. For example, it shows that the equation tan(α) = (v^2/rg) relates the angle of banking to the speed such that the horizontal forces balance. It then gives an example problem to find the favorable speed for a train around a banked curve with a given radius and rail dimensions.
