Strength of materials

Section properties and tensile, compressive and shear stress.

Section properties

Compute area, centroid, moments of inertia, elastic and plastic section moduli, radii of gyration, torsional constant and weight per foot of rectangles, tubes, W, C, L and T shapes and built-up sections.

I, S, Z, radius of gyration

Tension, compression and shear

Compute normal and shear stress in bars, pins and plates, elongation, strain, factor of safety on yield and ultimate strength and minimum area, with materials such as A36, SAE 1045, 304 stainless and 6061-T6 aluminum.

Stress, safety factor, δ = FL/AE
