The objective of this video is to consider more complex examples involving resolving of forces. First part of the video introduces with a diagram of a structural element subjected to two different forces and the fact is that the value of one force with its acting angle is not given which needed to be found out from the given values of another force and the resultant value of these forces. The acting angles both for another force and resultant force have been given.
Moving on, the video shows how to resolve the given forces into its components in x and y direction & subsequently determines the unknown force value solving the equations of obtained components forces. Later, the video uses the value of known angle and magnitude of forces to find out the acting angle of the respective force which working direction has not been given. This is quite a complex problem, so do practices to have better understanding on the lesson overviewed in this tutorial.
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.
