This video discusses about forces and their relevance to engineering followed by a brief explanation on different types of forces and units. Forces are some kind of influence which results in changes to the motion of objects & often cause accelerations to object having mass by changing in velocity with respect to time. Moving on, the video talks about the relevance of forces to engineering mechanics pointing out its application to deformation, velocity changes, deterioration of materials, deflections and bending. Through understanding of forces are crucial for physical aspects of engineering study.
Second part of the video discusses on different types of forces including forces due to gravity, point & distributed load, spring actions and internal forces. Later, the video introduces with the SI unit of forces which is symbolized by N (Newton). 1N is the force required to accelerate 1 kilogram of mass at the rate of 1 meter per second squared. Overall, the video tries to give a brief inside to forces and its types, understanding which is vital to have a strong basic for the study of engineering mechanics.
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.
