WebForce and stress Units of force. Force is measure in Newtons where 1 N is the force necessary to accelerate a mass of 1 kg by 1 m/s 2. Units of stress. In structural geology we are almost always interested in what a force does to some part of the Earth’s crust, so we need a measure of force concentration or force per unit area. This is stress. WebStress: It is the force applied to an object which is divided in terms of its cross-sectional area. σ = F/A. Where , F = force. A = cross sectional area. Stress is nothing but the distribution of the force that is applied when the object is loaded. When there is the distribution of the forces internally it balances the reaction.
