In this tutorial, the video presents a comprehensive example of static friction where it asks to find the coefficient of static friction based on the data given. First part of the video vividly illustrates the given problem where it has shown that a block of 10 Kg mass is rest upon on an inclined surface & the slope of the surface is given as 30 degree. The gravitational acceleration is also given as 10m/s2. Moving on, the video draws the FBD showing the actions of gravity force, normal force and friction force. In addition, the required angles of these forces are also shown over the FBD.
Next, the video applies the equilibrium principle and resolves force components into x & y direction and successively computes out the unknown values from the established equations. Later, the video introduces with the equation of static friction overviewed in the previous video & finally determine the coefficient of static friction putting the required values into the equation. Do on hand practices with the tutorial to have better understanding on the workout completed in this lesson.
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.
