Static Friction Example | Statics

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.
