WebRemember that, as conductors are usually circular in section, the cross sectional area may need to be found using the basic formula for the area of a circle. i.e. A = π r 2 or A = π (d/2) 2 where r and d are the given radius and given diameter, respectively, and π = … WebResistivity, commonly symbolized by the Greek letter rho, ρ, is quantitatively equal to the resistance R of a specimen such as a wire, multiplied by its cross-sectional area A, and divided by its length l; ρ = RA /l. The unit of resistance is the ohm.

F is the force and A is the surface area. In SI units, force is measured in newtons and area in square metres. This means stress is newtons per square ... Webtensile strength, maximum load that a material can support without fracture when being stretched, divided by the original cross-sectional area of the material. Tensile strengths have dimensions of force per unit area and in the English system of measurement are commonly expressed in units of pounds per square inch, often abbreviated to psi.
