The objectives of this video are to define a simple truss followed by a concise discussion on design assumptions of trusses. First of all, the video gives the definition of simple truss stating that a truss which begins with a triangular element and which can be expanded by adding two members & one joint as well as which meets relationship formula between members and joints is basically known as simple truss. The video introduces the stated relationship formula while giving the definition.
Moving next, the video shows different types of trusses structures and examines whether they are simple truss or not. Later, the video talks about the design assumptions needed to consider in doing the design of simple trusses e.g., all loads are applied at joint, self-weight of members are negligible & members are connected by smooth pins. Overall, the video tries to give a brief overview to simple trusses & design assumptions understanding which is must for the study of engineering mechanics.
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.
