How do you calculate tensile strength?
Tensile strength isn't really measured; it's calculated. It is explained as the point at which a sample of material fails when subjected to tensile stress. The unit of measure of tensile strength (and stress) is the Newton per square meter (N/m2), also called as the Pascal (Pa). Tensile strengths of various building materials, like steel, are measure in millions of Pa.
Take the difference among your experimental value and your known value, and divide that difference by your know value. Say you experimentally found the force of gravity to be 8m/s
