What has engineering ever done for us?

“What has engineering ever done for me?” Well… Clean water. Electricity. Cars. Trains. Aircraft. Heating. The internet. Smartphones. Modern medicine. Buildings. Manufacturing. Energy. But apart from all THAT… 😂 It’s quite remarkable how much of modern li

We’ve calculated the resultant force as 500 N. But that’s only part of the answer. Why? Because a force needs both a magnitude AND a direction. We already have the magnitude. Now we need the angle. Using the same 300 N and 400 N forces from the previous video, I’ll show you how a

You will 100% need this in engineering.

Here’s where Pythagoras becomes genuinely useful in engineering. You have two forces acting at 90°: ➡️ 400 N ⬆️ 300 N But you don’t know the resultant. Because the forces form a right-angled triangle, we can use Pythagoras to find the missing side. 300² + 400² = R² R = 500 N.

Do you need to be brilliant at maths to study engineering?

Do you need to be brilliant at maths to study engineering? I don’t think you do. What matters is learning how to USE the maths. What is the problem? What information have I been given? What am I trying to find? Which formula do I need? Does my answer actually make sense? Bre

Was Pythagoras an Engineer????

400 N to the right. 300 N upwards. What’s the resultant force? Here’s the catch… You can’t just add them and say 700 N. When two forces act at 90°, there’s a simple bit of maths that gives us the answer — and if you remember Pythagoras, you’re already halfway there. 👉 Follow me fo

Here’s an engineering question that looks almost too easy:

Here’s an engineering question that looks almost too easy: 500 N pushes an object to the right. 500 N pushes it to the left. So what’s the resultant force? The answer is 0 N. But here’s the more interesting question: What does a ZERO resultant force actually tell us about the obje

Maths cannot read your mind.

Maths cannot read your mind!! Two forces are pushing in the opposite direction. 300N one way and 200N the other way. The calculation itself takes seconds. But there’s one important part of the answer that’s surprisingly easy to forget. I’ll show you exactly what it is in this short l

Two force into one! But how?

Imagine two people pushing the same heavy object. One pushes with 300 N. The other pushes with 200 N. What’s the overall force acting on it? The calculation is simple — but the engineering idea behind it is much more important. It’s called the resultant force. And once you underst

There’s a strange misconception about engineering.

There’s a strange misconception about engineering: The more complicated something looks, the cleverer the engineering must be. Not necessarily. Some of the hardest engineering involves taking a complicated problem and producing something that’s simple, reliable and easy for anyone to use.

This looks hard but it’s not!!

Here’s your challenge: An electric motor produces 50 Nm of torque at 1,500 RPM. Calculate its power in kW. Don’t hunt through the equation sheet yet. Ask yourself one question: Can I use RPM directly in P = Tω? That tells you what your first step needs to be. In this final less

Engineers Ask One Question You Probably Don’t

Most people look at something and ask: “How does it work?” An engineer also asks: “How could it fail?” 👀 That’s when engineering gets really interesting. What’s something you use every day that you’d REALLY rather didn’t fail? 😂👇 ⚙️ Want to learn more about engineering? Tap my nam

Two numbers can tell you the POWER of a rotating machine.

Two numbers can tell you the POWER of a rotating machine. Torque. Speed. Put them together and you get this… Torque tells you the turning effort. Angular velocity tells you how quickly it’s turning. Put them together: P = Tω …and now you can calculate the power of a rotating

This formula scares students more than it should.

This formula scares students more than it should. Give me 60 seconds and I’ll show you where every part of it comes from. TikTok caption RPM to rad/s. It looks like one of those conversions you’re supposed to magically remember. Don’t. Understand where the 2π and the 60 come from

Why does a longer spanner make a stubborn nut easier to turn?

Why does a longer spanner make a stubborn nut easier to turn? You haven’t suddenly become stronger. You’ve increased the torque. In this short lesson, I’ll show you the simple relationship between force, distance and turning effect — without making it more complicated than it needs to be.
