WebA couple is a pair of forces that acts to produce rotation only. Unlike moments of a single force, the moment of a couple doesn’t depend on a pivot, only on the perpendicular distance between the two forces. A couple consists of a pair of forces that are: Equal in magnitude. Opposite in direction. WebDensity is given in g/cm3, so convert the volume of the gold bar into grams to match the units. 0.454 kg = (0.454 × 1000) g = 454 g Use the units given for density to help you decide what calculation needs to be carried out. The units of density are g/cm3, so divide the mass (g) by the volume (cm3). Or, write out the formula triangle.
