Error calculating outward normal
WebThe gradient ∇ f = 2 x a 2, 2 y b 2 is an outward normal to the level curves of this function, which are homothetic ellipses. Multiplying by a 2 2 and negating to get an inward normal, we get. n = − p x ′, r 2 p y ′ . (This can also be derived by implicit differentiation of the standard equation of an ellipse.) WebFor normal stresses, compression is positive. For shear stresses, positive stresses act in positive directions on negative faces (a negative face is one in which the outward normal to the face points in the negative direction).

WebFrom the video, the equation of a plane given the normal vector n = [A,B,C] and a point p1 is n . p = n . p1, where p is the position vector [x,y,z]. By the dot product, n . p = Ax+By+Cz, which is the result you have observed for the left hand side. The right hand side replaces the generic vector p with a specific vector p1, so you would simply ...
