Consider a simply supported beam under four-point bending which is illustrated in Figure 3-1 .If the cross-section of a beam is symmetrical about its neutral axis, the maximum tensile and compressive stresses are equal. Thus, the flexure formula (3-1) Becomes (3-2) where = the maximum tensile stress = the maximum compressive stress

To measure the in-plane deformation of a sheet of metal during a forming process, your managers place three small hardness indentations on the sheet. Using a travelling microscope, they determine that the initial lengths of the sides of the triangle formed by the three indents are 1cm, 1cm, 1.414cm, as shown in the picture below.

Figure 2 – Sheetmetal Bending Rolls. Machines used to bend sheet metal or plate into round or part round forms with either parallel or conical sides are called 'Bending Rolls'. Bending rolls for sheet metal are made in various sizes from the bench type for tin plate work to the larger pedestal types which are suitable for general sheet-metal ...

The bending stress for a beam with a hole in it, turns out to be twice what the nominal stress would be without the hole, based on the flexural formula. So, the general form of the equation is: Where M is the bending moment (derived above) = 8204.6 in-lbs.
