    Accelerated reference frames equation derivation question

    Also, zooming out a little, the diagram and proceeding equations and derivations are a part of depicting the rate of change of the principal axis vectors, which share an origin with the body axis vectors, of the accelerated reference frame. Also, to clarify, my question is regarding why we...

    Accelerated reference frames equation derivation question

    Explanation of Diagram: Q' is a representation of a 3D vector, vector Q, after a rotation of δθ about an axis, that axis being represented by vector n hat in the diagram. The angle between vector Q and vector n hat is represented as α. Explanation of the very first step: During the...

    Two springs from the ceiling attached to one mass, least energy principle

    [b]1. Suppose have a ball connected to a spring on each end – one with constant k, and the other with constant K. And suppose the springs are attached to the ceiling a distance d apart. Use energy minimization methods to determine the (x,y) coordinates of the mass in equilibrium – taking the...
