Two small disks A and B of mass 3 kg and 1.5 kg, respectively, may slide on a horizontal, frictionless surface. They a connected by a cord 600 mm long and spin counterclockwise about their mass center G at the rate of 15 rad/s. At t O, the coordinates of Gare x₁ = 0 and yo = 2 m, and its velocity is vo= (1.2 m/s)i +(0.96 m/s)j. Shortly thereafter, cord breaks; disk A is then observed to move along a path parallel to the y axis and disk B along a path which inters the x axis at a distance b=7.5 m from O.

Power Transmission Elements

It is defined as the energy transfer from one location to another location. The energy will start moving from the energy generation source to the energy applied position to obtain the work output. From this method, a large amount of electric energy moves from the power station to various electrical substations.
