The breaking force is given by:
\(F_b=σ_b\times A\)
The tension experienced by the line is given by:
\(T={F_b\over SF}\)
where, Fb = Breaking force
σb = Breaking stress
A = Cross-sectional area
SF = Safety factor
Calculation
Given, σb = 4000 kg/cm2
A = 2 cm2
\(F_b=4000\times2=8000 \space kg\)
\(T={8000\over 4}\)
T = 2000 kg
