How It's Made Rubber Gloves Surgical rubber gloves were first implemented at Johns Hopkins Hospital. Watch this video to see how rubber gloves are made. 02:59.
If the mass m is measured in kilograms and the acceleration a is measured in meters per second squared, then the unit of force is kilogram x meter/second squared. This unit is called the newton: 1 N = 1 kg x 1 m/sÂ².
W = p * V We can do a quick units check to see that pressure force / area times volume area * length gives units of force times length which are the units of work W = (force / area) * (area * length) = force * length In the metric system the unit of work is the Joule, in the English system the unit is the foot-pound.In general, during a change of state both the volume and the pressure change. So it is more correct to define the work as the integrated, or summed variable pressure times the change of volume from State 1 to State 2. = p * V We can do a quick units check to see that pressure force / area times volume area * length gives units of force times length which are the units of work W = (force / area) * (area * length) = force * length In the metric system the unit of work is the Joule, in the English system the unit is the foot-pound.
