RP4 tells us a lot about force, IN GENERAL. Let’s briefly look at a few SPECIFIC forces. Many of these will be considered in detail in later episodes. We are all familiar with the force of gravity. On Earth, gravity gives things weight. It is a force (measured in newtons, as are ALL forces) that

It’s everywhere, and yet nowhere. You find it on Earth, but not in the dead of space. Yet it keeps you from floating into space. This is the power of gravity. Join us as we explore gravity in all of its elements. 9. What Is Gravity? So what exactly is gravity? I’m sure you have

Nuclear energy and nuclear technology are extremely important in today’s society. Around 10% of the world’s electricity is generated from nuclear power plants, and despite increases in renewable energy over the last decade, nuclear power is going to play a continued role for a long time yet, and that’s because nuclear power is a form

Newton’s 2nd law example number 1, the easy case. Recall, Newton’s 2nd law: you have unbalanced forces, implying that the net force is not zero, meaning that the object is accelerating. In the case where the unbalanced forces don’t exist, ie you’re in equilibrium, the acceleration is zero. Trivial example #1. Let’s suppose I have

Shear force and bending moment diagrams are powerful graphical methods that every mechanical and civil engineer should know how to use to analyse a beam under loading. In this video I’ll explain exactly how to master these diagrams, and we will see how they can be used to understand how a beam is loaded. I
