The objective of this video is to clear the moment concept followed by a workout on simple moment calculation. First of all, the video gives the definition of moment stating that moment is equal to the product of forces time distances. According to SI unit, the force is calculated by unit N (Newton) and distance is calculated by unit m (Meter). This makes the SI unit for moment is Nm (Newton-meter). The term moment is also described as being torque in the mechanics of solids.
Moving on, the video displays a figure illustrating the given data where it has asked to calculate the moment developed in a point 3m away from the applied vertical force, 10N. The video shows the moment calculation both by taking moment at clockwise & anticlockwise direction. Later, the video briefly shows what happens in moment calculations when a force is applied parallel to the point at which moment is needed to be calculated. Finally, the video concludes the facts that moment is only related to these forces which create rotation and rest forces just create axial forces.
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.
