This video, continuation of the earlier video, very first clears it objective to find the internal forces i.e., axial, shear and bending at midspan of the given exemplary beam considering the section to the right of the cut. After showing off the schematic of exemplary beam, the video examines section of right cut followed by the drawing of FBD. Next, the video applies the equilibrium principle to obtain forces and moments equations. Doing so, the video explains all the facts and figures in details.
Moving on, the video computes the unknown values of internal forces and subsequently verifies the results with the previously obtained results from section to left cut. Later, the video talks about the importance of considering a cut that minimize the computation time to find out the unknown values especially in exam. The method of sections is quite tricky, so better understanding on this method is very significant in doing many complex workouts 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.
