The objectives of this video are to discuss about circular motion followed by a brief introduction to cylindrical coordinates. First of all, the video gives introductory overview to motions in cylindrical coordinates successively pointing outs the diversity of Cartesian coordinates system and cylindrical coordinate system in defining position, velocity and acceleration with reference to time. Moving on, the video expresses a circular motion over the cylindrical coordinates system where two important components- angle and radius vectors are used to describe the motion of any body at any time.

Next, the video introduces with unit vectors used in cylindrical coordinate and successively derives the equations used to represent the expression of velocity at any time. Doing so, the video describes the radical components and transverse components with their expressions elaborating all the facts & figures in details. The video uses the differentiae concepts of calculus to express the formulae of circular motion over the cylindrical coordinate- understanding which is very important to work out on different problems related to the branch of kinematics of engineering mechanics.

### Course Description

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.
