RS TENSILE PVT IN DELHI Tensile stress is a physical quantity related to tensile forces and stretching actions. It causes the elongation of any material along the axis of the load applied to the material. It is a state in which the load applied to an object tends to pull or stretch the material along the line of application of the force. Tensile strength is often referred to as ultimate tensile strength and is calculated by dividing the peak tension force the sample withstands by its cross sectional area. A tensile tester is used to measure tensile strength. A load cell is fitted to the tensile tester to measure tensile force.
