The objective of this video is to do a comprehensive workout on more complex moment calculation. Very first, the video describes the problem showing a free body diagram of a beam subjected to two different forces - one acting perpendicularly at leftmost point of the beam and the second one acting at rightmost point of the beam with an angle 45 degree. The beam is 12 meter long and a point ‘B’ is located 4 meter away from the rightmost end of the beam. The video asks to determine the moment at point A (leftmost end of the beam) and point B.
Moving on, the video briefly shows how to resolve force components in x & y direction of the given inclined force. Next, the video shows the moment calculation at point A considering anticlockwise rotation caused by the applied forces explaining all the facts in details. Later, the video shows the moment calculations at point B considering the rotation caused by resolved forces in anticlockwise direction. Overall, the video tries to clear how to do moment calculations for complex setbacks.
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.
