This video presents a comprehensive example of finding resultant vector as a mean of magnitude & direction resolving three given vectors. First of all, the video illustrates the example vividly where it has shown that three different forces are acting on a object at different angle with the coordinates & each of the forces are varied in magnitude. Next, the video talks about the procedures to obtain the resultant vector using unit vectors concepts and resolving the given vectors into x & y components.

Moving on, the video shows how to resolve the given vectors into x and y components explaining all the facts and figures in details. The video, then, sum up all x and y components vectors separately & applies parallelogram formula to determine the magnitude and angle of the resultant vector. Later, the video shows the resultant vector in terms of magnitude & angle in the given exemplary figure.

Course Description

Mechanics, the study of forces and physical bodies, underpins a very large proportion of all forms of engineering. A thorough understanding of mechanics is essential to any successful engineer. This course helps develop an understanding of the nature of forces with consideration for how they may be simplified in an engineering context. The conditions of equilibrium are then used to solve a number of problems in 2D and 3D before moving on to a broad range of topics including centroids, distributed loads, friction and virtual work. The course will also provide an introduction to dynamics, with a particular focus on the effects that forces have upon motion.
