WebJust like stress, there are two types of strain that a structure can experience: 1. Normal Strain and 2. Shear Strain. When a force acts perpendicular (or "normal") to the surface of an object, it exerts a normal stress. When a force acts parallel to the surface of an object, it exerts a shear stress. Let's consider a rod under uniaxial tension. WebMay 9, 2024 · The resulting equation for the vertical shear of the left side of the beam as a function of x becomes. V = F + m g 2 − m g x L. At the point of application of F the vertical shear is undefined, crossing the zero point and becoming negative. For the right side of the beam the shear equation is. V = − ( F − m g) 2 − m g x L.
