The objectives of this video are to discuss about shear stress & to work out on finding shear stress in a rivet joint. First of all, the video clears the concept of shear stresses which is the result of forces applied along the same plane as the cross-section. It can also be described as a rubbing force. Next, the video illustrates the shear stress vividly representing a schematic of a structural member that is subjected to a couple. Moving on, the video presents an example of finding shear stress developed in a rivet that connects two structural members.
Both the members are subjected to point loads of 5 KN acting at free end parallel with the members. Moving next, the video illustrates how shear stress is developed at rivet joint due to the actions of applied axial forces and successively draws the free body diagram for it. Later, the video gives input to the respective equation and determines the value of shear stress. It is highly recommended to do on hand practices to have a good grasp on the content described in this lesson.
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.
