Example - Maximum Safe Mass for a 3/8" Polypropylene Fiber 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 3/8" polypropylene fiber rope where safe load is 0.9 kN can be calculated as

m = (0.9 103 N) / (9.81 m/s2)

   =  91.7 kg
