Free Body Diagram

Recently, I’ve been revisiting some basic statics problems, especially those involving force resolution. In this post, I will walk through types of forces, and how to construct free body diagram and solve the equations with some of key principles and guidance with figures. I also provided classic example of understanding Newtons Laws of Motion with an example. Types of Forces Here are some of the fundamental forces you’ll encounter while constructing free-body diagrams: ...

As part of Engineering Mechanics Series. Here is first problem we are going to solve. In case if you need some basics , Please visit this post as quick review Here is an given problem Ask Find maginitude and direction of Force P Find the contact force at bottom of block (say N) Assumptions Block is in equilibrium - i.e. block is at rest or moving at constant velocity Frictionless surface - there is no frictional force involved. Given data Mass of block (M) is 100 lb The force P is $10°$ inclined to horizontal The surface is inclined at $25°$ to horizontal base In order to draw free body diagram follow these steps Isolate the object - i.e. No external force or internal force. Imagine block is floating in space ...
