The objective of this video is to resolve vector to solve an engineering relevant problem. First of all, the video briefly illustrates the given exemplary figure of tower that is supported by 2 cables from opposite directions- one cable acts at an angle of 45 degree with the ground having 10 KN tension from right side & another one acts at an angle of 70 degree from left side. The video asks to find out the force exerted in left side cable. The height of the tower is given as 20 meter.
As the tower is stable at its position, so for equilibrium forces at left side must have to be equal with the forces acting from right side of the tower. Using this principle together with applying of vectors resolving technique, the video step by step shows how to determine the tension force exerted in the cable used to give support the tower from left side.
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.
