Figure $\PageIndex{19}$: If all the vectors normal to a cylinder point outward, then this is an outward orientation of the cylinder. Exercise $\PageIndex{11}$ WebStep 1: Parameterize the surface, and translate this surface integral to a double integral over the parameter space. Step 2: Apply the formula for a unit normal vector. Step 3: Simplify the integrand, which involves two vector-valued partial derivatives, a cross product, and a dot product. WebIf the normal unit vector n of the surface (pointing from Q towards P) is assumed fixed, the normal component can be expressed by a single number, the dot product T · n. This number will be positive if P is "pulling" on Q (tensile stress), and negative if P is "pushing" against Q (compressive stress) The shear component is then the vector T − ( T · n ) n . dynamic strain measurement
