The objectives of this video are to discuss the concept of unit vectors & resolves vectors into x and y components followed by a brief discussion on vectors as a magnitude and angle. A unit vector is the vector having magnitude one and are often parallel to the coordinate axes pointing toward positive value of the coordinate. The unit vectors are useful as they ease the way to turn magnitude to vector by giving directions. Using the concept of unit vectors, the video resolves the given multiple vectors in x and y components and subsequently shows how to add those together.
Moving on, the video introduces with vectors operations as a means of magnitude & angle over the Cartesian coordinates. Subsequently, the video briefly illustrates how to find the value of magnitude of resultant vector & angle of the resultant vector formed by the original given vectors. Overall, the video tries to give a brief inside on unit vectors & its’ uses on doing vectors operations to the depth- understanding which is must to move forward with the course of engineering mechanics.
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.
