The objectives of this video are to discuss 3-D axes followed by a brief introduction to plotting of 3-D vectors. At first, the video clears the concept of 3D axes graphically illustrating a coordinate frame having three axes respectively at x, y & z direction. Each axis is located at right angle from the other two axes. The video shows the three planes e.g., xy, yz & zx formed because of 3D axes sketching the region over the coordinate frame. It is necessary to have clear concept on 3D axes to understand the workouts on 3D vectors in doing the study of engineering mechanics.
Moving on, the video shows how to plot a point in 3D coordinates system followed by the plotting of 3-D vectors. Doing so, the video shows how magnitude and direction of vectors impacts on plotting & subsequently shows how the resultant represents the final coordinates of the 3-D vectors in a 3-D plot. Overall, the video tries to give a brief inside to 3-D vectors plotting which is quite simple yet very important for doing different operations of vectors over the 3-D coordinates system.
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.
