WebCentripetal force, for an object in circular motion, is just the force maintaining the circular motion, the force that prevents the object from flying away tangentially. Unless this force is present, no object can execute a pure circular motion, because in absence of a force, a body moves uninterrupted along a straight line (Newton's first law). WebMohr–Coulomb theory is a mathematical model (see yield surface) ... Mohr's circle is used to determine which principal stresses will produce this combination of shear and normal stress, ... is often called the cohesion and the angle is called the angle of internal friction.
