2) Sketch the bending stressdistribution over the cross section on which the maximum bending stressoccurs. (3) Compute the bending stress at a point on section B that is 25 mm below the top of the beam. and the distance c between the neutral axis and the top (or bottom) of the cross section is c = 100 mm = 0.1 m.

Hey,
Step 1
Calculate the bending moment, represented by "M." The bending moment, or the force required to bend the object, can be found using formulas specific to the type of object being bent.
Step 2
Calculate the moment of inertia, represented by "I." The moment of inertia, which is the object's resistance to change in its rotation, depends on the cross-sectional shape and thickness, not its length or makeup. For a rectangular solid object, I = (b*h^3)/12, where "b" is the width of the cross-section, and "h" is the measure of the cross-section in the direction force is being applied.
For a round solid object, I = (pi*r^4)/4, where "r" is the radius of the cross-section.
Step 3
Determine the distance between the neutral axis and the outer surface where maximum stress occurs. This is represented by "c."
Step 4
Calculate maximum surface stress, or MSS, using the following equation: MSS = (M*c)/I
