Kinematics PART 5

Continued from p.629 M.E.4755 November 1 Calculus can be used to derive formulae for various engineering phenomena. Earlier we mentioned the equations of rotational motion, observing that whereas in linear motion the mass of an object is a measure of its inertia, or capacity to resist linear acceleration, for rotational motion the moment of inertia is used, being a measure of a body's capacity to resist rotational acceleration. The moment of inertia depends on which axis of a body is assessed – it takes little torque to twist a drum-major's baton around its longitudinal axis but much greater torque to twist it at around its middle. In the latter case most of the mass of the baton is further away from the axis of rotation and is thus able to…
