Permissible Stress in Steel for fe 500

Answer: C. 275 N/mm2

Permissible bending tensile stress in steel for fe 500 is 275 N/mm².

Solution

Permissible bending tensile stress can be calculated as 0.55 times to the yield strength.

So, Permissible bending tensile stress for fe 500 = 0.55500=275 N/mm²

Permissible bending tensile stress for fe 415 = 0.55415=228.5230 N/mm²

Permissible compressive stress for fe 415 = 190 N/mm².
