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.
The SI unit of force is the newton (N), defined as N=kgms 2, and the ac-celeration of gravity is 9.81 m/s 2. The weight per unit length of a W250Ã115 beam is w=115kgm9.81ms 2 Ns 2 kgmkN10 3 N=1.13kN/m. If the beam is 4 m long, then the total weight, W, of the beam is W=wL=1.13kNm4m=4.51kN.
