The objectives of this video are to discuss about what is truss and why do trusses are used. First of all, the video looks into truss clearing the concept that trusses are basically converts external loads into axial forces. This is done because materials such as steel & concrete can resist much larger axial forces than shear & bending moments. Therefore, trusses are designed eliminating shear & bending as much as possible so that they can take just axial loads. The video, then, quickly look at an analogy to describe the facts and figures of trusses in greater details.

The analogy involves the axial loads translation in a beam and column followed by a presentation of simple truss where loads act axially over the structure. Moving on, the video briefly discusses how the external loads transmit axially explaining the facts of shears and bending moments. Overall, the video tries to give an introduction to trusses understanding which is very important for the study of engineering mechanics. At end, the video refers to watch next video for workouts on trusses.

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.
