There are some quite serious sites that point out the importance of units in engineering calculations, but a less serious result of an error is the guy who got the wrong slipper! See the news report here.
This shows the deflection and bending moment history of a propped cantilever loaded with a point load at mid-span. The beam has a plastic moment capacity of 100 kNm and a shape factor of 1.12. A strain hardening modulus of 2% of the modulus of elasticity is used. The model is based on that given […]
