The objectives of this video are to draw the axial force diagram (AFD), shear force diagram (SFD) & bending moment diagram (BMD) for a given exemplary beam. First of all, the video shows the given exemplary beam having a roller support at 2 m away from left end and a fixed support at right end. The beam is subjected to three different loads- a point load of 10 N acting downward in direction at left end, a point load of 5 N acting parallel with the beam at left end & a uniformly distributed load of 2 N/m acting across 6 m length of the beam from the right end.
Moving on, the video draws the free body diagram and establishes equilibrium principle to find out the unknown values of reactions forces. Next, the video at 2nd step makes cuts at critical points to develop equations representing internal forces to use afterwards to draw the SFD & BMD. Later, the video shows the conversion of UDL to point load and subsequently develops moment equations to find moment at arbitrary points. Finally, the video refers to watch next video to continue the 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.
