The objective of this video is to use the method of joints to find axial forces in members of a simple truss. At first, the video presents the given exemplary simple truss asking to find the axial forces in two arbitrary members using the method of joints. The given truss has 7 members & 5 joints. Each of the members is 3 m long & the angles between members are also given. The truss has subjected to two axial loads- one of 10 N at left-top joint and another of 15 N at right-top joint.

Moving on, the video shows how to compute the distance of the joints subjected to axial loads from left-bottom end of the truss. Next, the video draws the FBD of the given truss, determines supports reactions forces using the principle of equilibrium. Once all the unknown values are computed out, the video considers left-bottom joint to find the axial forces developed adjacent to that joint. Later, the video uses the obtained values to determine the axial forces developed adjacent to left-top joint.

### 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.
