Introduction

### Course Review: Mastering Statics on Coursera If you are looking to deepen your understanding of mechanics and embark on a journey to mastering the principles of statics, the Coursera course **"Mastering Statics"** offers a comprehensive and well-structured pathway. This course is tailored for students, engineers, and anyone interested in the foundational principles of statics, a subfield of mechanics that deals with objects at rest under the influence of forces. #### Overview The course opens with an engaging introductory video that sets the stage for what lies ahead. Through detailed lectures and practical problem-solving exercises, learners will explore the conditions necessary for an object to maintain equilibrium when subjected to static forces. This is particularly critical for understanding how structures behave under loads, making it a vital course for aspiring civil and mechanical engineers. #### Course Syllabus Breakdown 1. **Understanding Forces and Moments**: In this initial module, you'll dive into the heart of statics, beginning with Newton’s Laws of Motion. The course methodically introduces forces and moments, equipping you with the vector algebra required to solve real-world statics problems. 2. **Equivalent Systems of Forces and Equilibrium**: This module shifts focus towards systems of forces and the criteria for equilibrium. You'll learn vital concepts, such as identifying the components necessary for a rigid body to achieve static equilibrium — knowledge that builds a robust foundation for more complex topics. 3. **Stability and Static Determinacy**: Understanding stability and static determinacy is pivotal yet often overlooked in traditional textbooks. This module clarifies these critical concepts through intuitive explanations and practical examples. 4. **Trusses**: Trusses are key to modern engineering, found in everything from bridges to cranes. The course introduces two analytical methods — the method of joints and the method of sections. Moreover, a computer-aided approach will be taught, shedding light on contemporary techniques used in structural analysis. 5. **Area Properties and Moments of Inertia**: To analyze complex structures, one must grasp area properties and moments of inertia. This module teaches how to convert distributed loading into concentrated loads and how to calculate moments of inertia—both essential skills for static analysis. 6. **Internal Force Diagrams**: The course takes a crucial step into analyzing frames and beams for internal forces. You will learn to create axial, shear, and moment diagrams using conventions that are widely accepted in the engineering field, enhancing both your analytical and visualization skills. 7. **Static Analysis of a Structure**: The final module presents real-world applications through complex frame analysis. You will be challenged to apply everything learned to accurately calculate and plot internal force diagrams, ensuring proficiency in handling intricate static problems. #### Why You Should Enroll **Mastering Statics** stands out for its structured and methodical approach blended with practical application.

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.

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.

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 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.

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.

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.

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.
