Solving a ramp problem is made much easier by tilting the x and y axis so that the x axis is parallel to the ramp. This video shows you how to tilt the axis and the relationships between forces that appear.
You really helped me a lot; I got in doubt about a problem where there was a rope pulling a man up in an inclined plane, but now all makes sense, thanks a lot!
Hey there, I have a doubt. Isn't the vertical component of the force sin(theta) and the horizontal cos(theta)? If so why are we taking the components as vice versa? Is it because we tilted the axises?
Ok I think I got it now, I was confused because I only solved problems of projectile motion where this held true. But cos(theta) as you explained should be adjacent and sin(theta) opposite. Is that it?
@@festive5476 Yes, sin will always be the opposite over hypotenuse and cos will always be adjacent over hypotenuse, so that's why the y axis has cos and the x axis has sin. Although sin is related to y and cos is related to x, you always follow SOH CAH TOA.
I have to say a lot of people have been asking this question. No, really. A lot of people come up to me and they ask me. They say, 'What's 2+2?' And I tell them look, we know what 2+2 is. We've had almost eight years of the worst kind of math you can imagine. Oh my god, I can't believe it. Addition and subtraction of the 1s the 2s and the 3s. Its terrible. Its just terrible. Look, if you want to know what 2+2 is, do you want to know what 2+2 is? I'll tell you. First of all the number 2, by the way I love the number 2. It's probably my favorite number, no it is my favorite number. You know what, it's probably more like the number two but with a lot of zeros behind it. A lot. If I'm being honest, I mean, if I'm being honest. I like a lot of zeros. Except for Marco Rubio, now he's a zero that I don't like. Though, I probably shouldn't say that. He's a nice guy but he's like, '10101000101', on and on, like that. He's like a computer! You know what I mean? He's like a computer. I don't know. I mean, you know. So, we have all these numbers and we can add them and subtract them and add them. TIMES them even. Did you know that?
