The objective of this video is to analyze a complex frame to deduce forces on individual members. First of all, the video vividly illustrates the given complex frame and asks to find reactions at A & F. The frame has four members- ABC, CD, DEF & BE which is subjected to two point loads- one of 60 N at point C parallel with the member CD and another of 100 N at midpoint of the member CD acting downward in direction. The frame has been supported by two hinge supports at point A & F. All the necessary dimensions are given representing the locations of different points in the frame.

Moving on, the video draws the free body diagram of the given complex frame and applies the law of equilibrium to get moments and force components equations. Doing so, the video has to examine different members of the frame and to relate the obtained equations to finally determine the values of reactions at point A & F. It is highly recommended to do on hand practices with this tutorial video to have better understanding on the solution of harder frames example overviewed in this lesson.

### 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.
