Document Summary

Flectse do all work on handout and boxflnal izuinerical answers. [5] the fundamental units in the si system are the kilogram (kg), meter (rn), and second (s) with the fundamental dimensions being mass [ml, length [lj, and time [t]. A newton is a derived unit equal to kg . rn/s2 and has dimension [m][lj[tf2 . This is a good way to check your work. is important a. [2] consider the rotation formula ft = ia , where f is a force, 1 is the length of the moment arm, i is a mass moment of inertia and a is an angular acceleration in radians/s2. According to this lbnnula, what are the si units and. [3] a fellow student tells you that the fonnula for the period of oscillation, r , of an inverted pendulum supported by a spring with spring constant, k, is given by r = 2ir - . If not, suggest a possible coltection to the fonriula.
