Problem 6 A portion of a mechanical coin sorter works as follows: Pennies and dimes roll down the 200 incline, the last triangular portion of which pivots freely about a horizontal axis through O. Dimes are light enough (2.28 grams each ) so that the triangular portion remains stationary, and the dimes roll into the right collection column. Pennies, on the other hand, are heavy enough (3.06 grams each) so that the triangular portion pivots clockwise , and the pennies roll into the left collection column. Determine the moment about O of the weight of the penny in terms of the slant distance s in millimeter s. 9.5 mm 3.5 mm pennies dimes

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.
