Through Engineers' Eyes - Introducing the Vision: Engineering Mechanics by Experiment, Analysis and Design

Learn the basic techniques of engineering mechanics and use them to interpret experiments and make designs that will work.

Through Engineers' Eyes - Introducing the Vision: Engineering Mechanics by Experiment, Analysis and Design
  • Duration4 weeks
  • Weekly study4 hours

When you design anything, how do you know that the design will work?

Engineering mechanics is the science-based analysis that engineers use to predict how their designs will perform. It is vital to ensure engineers can meet their responsibilities for performance and safety.

In this course and its companion course Through Engineers’ Eyes: Expanding the Vision, you will learn analytical skills, use them to understand experiments and apply them in design. Through experiments, analysis videos, paper and pencil tutorials and adaptive tutorials, you will experience living in the engineer’s world.

Skip to 0 minutes and 10 seconds Before the first rivet was hammered, they knew that this bridge could take the load. Well before the very first takeoff run, they knew that this aircraft would fly. When you design anything, how do you know beforehand that it will work? Livelihoods depend on it. Lives do too. It’s an awesome responsibility. To meet it, you need to look at the world through engineers’ eyes. And to get engineers’ eyes, you need engineering mechanics. Engineering mechanics starts with physics– forces, equilibrium, acceleration, gravity. This helps you to understand the world. That’s Classical Mechanics. Engineers developed their own version to help them change the world, to help them design. That’s Engineering Mechanics. But for engineers, it’s more than that.

Skip to 1 minute and 11 seconds Engineering Mechanics is built into their souls. It colours everything they see around them. When they look at the bridge, they think forces and bending motion. They feel stresses and strains. When they see an aeroplane fly, they visualise the lift forces that defy gravity. With just a little mathematics, in this course you’ll learn some basic engineering mechanics. You’ll learn by experiments, analysis, and design. And you’ll start to see the world through engineers’ eyes. But be prepared. Once you’ve opened your engineers’ eyes, there’s no going back. Get ready for a life-changing experience.

What topics will you cover?

  • Week 1: The nature of loads, springs and other elastic behaviour, static and dynamic loads
  • Week 2: Force as a vector, Free Body Diagrams, Equilibrium of forces that act at a point
  • Week 3: Twisting effect of a force, Couples, Torque
  • Week 4: Equilibrium of two-dimensional rigid bodies and systems of rigid bodies

What will you achieve?

By the end of the course, you‘ll be able to...

  • Describe how to manipulate forces as vectors
  • Apply techniques and skills in using free-body diagrams and equilibrium to analyse and predict forces;
  • Explore how engineering mechanics is used in design
  • Describe and calculate the twisting effect of a force

Who is the course for?

This course is for anyone interested in engineering mechanics. Learners will need to have basic mathematical skills and access to a scientific calculator.
