Maximum Safe Mass for a 1/8" Wire Rope
The relationship between mass and force (weight) can be expressed as
m = F / g (1)
where
F = force, weight (N)
m = mass (kg)
g = acceleration of gravity (9.81 m/s2)
Maximum safe mass for a 1/8" wire rope where safe load is 2.45 kN can be calculated as
m = 2.45 (kN) x1000 / 9.81 (m/s2)
=249.75kg
