## Overview

##### Class Central Tips

Statics is the most fundamental course in Mechanics.

In this course, you will learn the conditions under which an object or a structure subjected to time-invariant (static) forces is in equilibrium - i.e. the conditions under which it remains stationary or moves with a constant velocity-.

You will also learn how to calculate the reaction forces as well as the internal forces experienced throughout the structure so that later you can properly design and size the foundation and the members of the structure to assure the structure’s safety and serviceability.

This course is suitable for learners with interest in different Engineering disciplines such as civil engineering, architecture, mechanical engineering, aerospace.

Non engineering disciplines may also find the course very useful, from archaeologist who are concerned about the stability of their excavation sites to dentists interested in understanding the forces transmitted through dental bridges, to orthopedic surgeons concerned about the forces transmitted through the spine, or a hip or knee joint.

The content will be primarily delivered using light board. Prof. Katafygiotis is going to write and sketch with color markers directly on the board while facing you. You will have an exciting and interactive learning experience online!

## Syllabus

• Understanding Forces and Moments
• This module introduces the basic operations that learners need to know in order to solve statics problems, we will start by reviewing Newton’s Laws, then introduce Forces and Moments and provide an overview of the vector algebra that governs their operations.
• Equivalent Systems of Forces and Equilibrium
• We will study the effect of a system of forces and couples acting on a rigid body and will state the conditions of equilibrium for particles, rigid bodies and assemblies of rigid bodies. The number of independent number of equations that are necessary and sufficient for satisfying equilibrium will be clearly stated.
• Stability and Static Determinacy
• We will discuss the important notions of stability and static determinacy. These are concepts that often are not presented clearly enough in some of the textbooks, causing confusion to students.
• Trusses
• Trusses are in a sense the simplest structures to analyze, used widely in structures such as bridges, industrial roofs, and cranes. We are going to introduce two methods of analysis, namely the method of joints and the method of sections to determine the member internal forces. In addition, we will study a computer-aided method for analyzing trusses.
• Area properties and Moments of Inertia
• To be able to deal with more complicated structures and loading scenarios, we will learn how to replace a distributed loading with an equivalent concentrated one using its geometric properties, such as its area and centroid coordinates. We will also learn how to calculate moments of inertia about specific coordinate axes and how to calculate their corresponding values about another translated and rotated system of axes.
• Internal Force Diagrams
• We will get to the most important part, which is analyzing frames and beams to calculate their internal forces and to draw axial, shear and moment diagrams. Contrary to most textbook presentations, we will adopt a notation that is universally adopted by engineers when using moment diagrams.
• Static Analysis of a Structure
• In this module, learners will be presented two examples of complex frames for static analysis. Learners should be able to apply what they have learnt in the previous module, calculate and plot the internal force diagrams. By the end of this module. students will be able to correctly draw axial shear and bending moment diagrams of rather complicated frames.

I have learn so much in my classes with . He paces the class just right so you feel challenged but not overwhelmed. So many other classes you just read from a text book but in his classes asks questions and gets the students to respond which is both fun and promotes faster learning. He is patient and eager to help. I’m thrilled to have found his class!

Being engineering student it's difficult to understand the topics and lessons like this course statics. this course is one of my difficult Subject in engineering that's why I chose this course to enhance my mathematical ability and more techniques to learn about solving problems in this course. thank you very much Hong Kong University science and technology in great job done in teaching mastering statics.

A great course helped me alot really big thanks to professor Lmabros S. Katafygiotis , During the corona visrus ( COVID - 19) pandemic it became hard for me to learn statics as the college did not provide a good course for online studying but i searched online and found this free corse and it really saved me thanks again professor hope you have good time and stay safe.

The course was so neat and well defined, the lecturer keeps teaching with a great concern and much more interested which makes you to focus. The flow of the modules are smooth which keeps you in the way. My overall rate on this course is so far so good.

A complete course, with a medium-high level of difficulty. It can be improved by evaluating vector algebra concepts in detail and not complicating the sign convention in bending moment and shear diagrams.

The course taught by the professor is too good. It starts from the basics and covers the whole statics and all the concepts taught can be directly applied wherever applicable. I thank professor for this course. Except for some (1 or 2 ) mistakes in quizzes rest of the things are fine.

it starts froms the fundamentals and goes to detailed static problems with a very clear experssion and examples.

Great course.I would recommend every Civil engineer to do this course.Easy language & concept explained in the easiest way with the help of examples.

The course is excellent, I invested more time than I expected but It was worth it now I really understood concepts that I dind't have very clear. Take this course if you want to improve your skills with regard to structural analysis and statics in general, it's very helpul Thanks!!!!

THIS COURSE WAS REALLY HELPFUL TO ME. I WOULD DIFINITELY TAKE OTHER COURSES IN COURSERA. I HAVE ENOUGH TIME TO PRACTICE AGAINS AND AGAINS. THE PROFESSOR TEACHES REALLY CLEAR AND IN MY OPINION HE IS ONE OF THE BEST PROFESSOR OF STATICS

these course is awesome and interesting to do various type of problems and to increase knowledge. i have refereed to number of text books and the lectures are very good and explanation of basics is excellent.

In this course you will learn all the basics ! the professor is explaining everything with very good details ! I wish i had him as professor on the university too! take the course and enjoy mastering statics!
• Jeramie Lee

Jeramie Lee completed this course, spending 3 hours a week on it and found the course difficulty to be hard.

I think that this course really helps you ton understand how the simple structure being stable or not. It is very helpful for civil engineering or structure engineering in the unveristy course.

• The course was amazing. I have only compliments to give. I will be wishing Professor Lambros Katafygiotis to make more courses related to the structural area. His teaching is excellent!
