The objective of this video is to introduce and discuss curvilinear motions. Principally, a curvilinear motion describes a particle motions along a curved path. Generally, there are two cases included in curvilinear motion- projectile motion and circular motion. Moving on, the video gives overviews on position vector, velocity vector and acceleration vector which represent the conditions of a particle at any time. Next, the video briefly talks about the projectile motion which analysis has been carried out over the Cartesian coordinates breaking up horizontal and vertical components.
Later, the video talks about circular and other motions which analysis have been carried out in the polar coordinates system breaking down position, velocity and acceleration into r and θ. The other motions include the motions which paths are not totally circular. At end, the video shows how to do analysis of these motions in the polar coordinates system & finally refers to watch next video to get in touch with the workout lesson of projectile motions.
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.
