Mechanical FE Exam: Cross Product Problem Solution

Описание: Hi, thanks for watching our video Mechanical FE Exam: Cross Product Problem Solution!
This video is one problem from my FE Mechanical Prep Course for passing the Mechanical FE Exam.

In this video, we dive into how to calculate the cross product of two vectors, A and B. Unlike the dot product, the cross product results in a vector, and we'll walk through the process step-by-step. First, we construct a matrix with the unit vectors i, j, k in the top row, followed by the components of vectors A and B in the second and third rows. We then calculate the discriminant of the 2x2 matrices to find the components of the resulting vector, which will have three terms: i, j, and k. This tutorial explains the essential steps and highlights the importance of the correct order when computing the cross product.
