Question

a 160 KN force is applied as shown at the end of a W200x52 rolled-steel beam. The effect and of stress concentration, determine:

A) Stresses at pint b (section) of the beam at A-A location

B) Max and Min Stresses at that pint & angle of Max.

C) Whether the normal stresses in the beam satify a desgin specification that they be equal to or less than 150 Mpa at Section A-A

C) Whether the normal stresses in the beam satisly a design specification that they be eq 60 kN A' -L = 375 mm A
