The objective of this video is to solve harder support reaction problem. First of all, the video shows the diagram of given exemplary problem which is nothing but a beam supported by a roller support at left end and another pin support at 4 m away from the left end. Both the supports are working on the beam from upward direction. The beam is subjected to two different loads i.e., a point load of 30 KN acting downward at 2 m away from right end and a uniformly distributed load of 5 KN/m acting downward and over 2 m length of the beam from right end.
All the necessary dimensions are also given. Moving on, the video draws the free body diagram for the problem at first step explaining all the facts and figures in greater details. Next, the video shows how to establishes equilibrium condition & thereafter applies equilibrium principle to resolve force components in x and y direction to get forces equations. The video also shows how to take moments for such complex conditions and finally determines the unknown values of forces and moment.
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.
