# Stress, Strain and The Young Modulous

Calculate the tensile stress in a suspension bridge supporting cable of diameterr of 50mm, which pulls up on the roadway with a force of 15KN...?

The greatest tensile stress which steel of a particular sort can withstand without breaking is about 10^9Nm^-2. a wire of cross-sectional area 0.01mm^2 is made of this steel. what is the greatest force that it can withstand?

@timur,
A=3.14159*(50/2/1000)^2=0.0019 m^2

Allowable force=2E+9 nt/m^2*A m^2=1963knt=2000 knt
