What weight in kilograms will a lintol of clear span 1.2meters support if the lintols are rated at
44.. 97 KN and
20.56KN

Lmfao, uhm this is PSYCHICS, not PHYSICS.

Newton,

The unit of force in the meter-kilogram-second system, equal to 100,000 dynes. It is the force required to give an acceleration of one meter per second per second to a mass of one kilogram.

One newton (on Earth surface) is equal to:-

kilogram
0.1019716

44.97 KN times .1019716 equals = 4.5856628 kilos
20.56 KN times .1019716 equals = 2.096536
kilos
