The objectives of this video are to give an introductory overview to free body diagrams followed by a brief discussion on the importance of free body diagram in the study of engineering mechanics. A free body diagram is a diagram used to show the relative magnitude & direction of all forces acting upon on an object in a given situation. Each force arrow on the diagram is mostly labeled to indicate the exact type of force. Moving on, the video shows a problem where it has shown that a box is rest over an inclined surface & subsequently elaborates how to draw a free body diagram for that case.
Next, the video demonstrates another exemplary problem of a simply supported beam drawing the free body diagram for the given condition. Doing so, the video briefly talks about the magnitude and acting direction of different forces explaining all the facts & figures in details. Later, the video talks about the importance of FBD briefly which allows to identify the forces that act upon on an object & to express such an understanding through the construction of FBD. Never hesitate to contact with our expert tutors if you face any difficulties in understanding the lesson overview in this tutorial.
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.
