I've learned that if you "lay down" force to the angle (close the angle) that's when it's cos and when you "stand up" force (to 90 degrees) it's sin. It was easy for me to remember this that way :)

Thank you so much! You explain this topic so eloquently! The idea of taking the limit as sine theta and cosine theta go to zero is really helpful.

The best way anyone has ever explained me and after searching a lot i got this.

thanks a whole ton sir id been struggling with fbd but with you everything just falls into its place thank u sooo much

I appreciate the clarification. Before taking my exam, our instructor posted some example problems for us to do. In the multiple choice two of the answers was dependent upon whether you used cosine or sine, so this is very important that a person gets this right.

Agreed. I always struggled with some of these and mixed up which should be sin and cos several times. Unfortunately my professor never told us how to know the difference.

thanks sir that cos and sin problem was a real headache .......thanks for sorting that out

a super helpful and unique way to explain how to decide between the sin and cos vector of a force. thank you so much this channel is a lifesaver!

I was having difficulties in Statics with figuring out which trig function (sin, cos, tan) to use when breaking forces down into their x and y components, but with that quick little revisit to trig (which I had a shaky foundation on from High School) really helped me out. I was getting confused as to why components of force in the X had sine in them but now I see it just comes down to basic trig.

Thank you for engaging my utmost attention and for producing this work. You've enlightened me in numerous ways and foremost is probably the part about taking the limit of theta. I can now see were one to stand a wet wooden beam measuring, 16ft x 4in x 4in, on its end and then lean it slightly against a wall and the using your setup I can calculate how much force is pushing against this wall. Correct me if I'm wrong please. If I perform a press handstand and walk up a wall using the wall to support my balance, it's evident to me much of the mg will be passing through my fingers but a percentage of my body's mg will be transferred to the wall. If theta is close to zero then a good 99% of the total mg is going go through my hands to the ground. I've never had pointed out to me the idea of reducing the subject under analysis to a dot. Brilliant.

This is ridiculously helpful! So is it fair to assume that (in an inclined slope problem) the vector opposing the Normal force will always be the cos(theta) component?

You need to consider exactly how you've defined theta, and determine the trig terms accordingly. It isn't guaranteed to be the same each time.

Thank you for this 🙏🏻

Amazing, thank you.

Can someone explain what he's writing on? I've always assumed it must be some kind of clear window but you would think the writing would appear backwards? I'm so curious to figure this out

sir so that means that the mgsin theta we found is in the direction of x+ axis that's why its the same as the point of FBD of the body .I mean that we haven't yet found on the plane but on a line parallel to it. Sir thanks for the video and i hope you will clear my doubt soon.

Sir, is there any way (Math theorem), where we can decide where to take the angle θ? Please do me a reply.

Nice video. I have a question based on this video. If a block is at rest on the incline plane at an angle of 30 degrees, would the maximum frictional force that would allow the block to stay in place be calculated using 30 degrees, OR would we have to find the minimum angle of the incline plane needed for the block to slide before we can determine the maximum frictional force? That is, find that minimum angle and then substitute it in the formula for fs(max) = UsMgcos (minimum angle needed for block to slide)?

@carultch

4 жыл бұрын

Because normal force of a stationary object on an incline ends up being m*g*cos(theta), and the lateral component of the gravitational force attempting to make it slide is m*g*sin(theta), you'll notice that both trig functions appear here. At the critical angle where sliding initiates, m*g*sin(theta) = mu_s*m*g*cos(theta). Values of m and g both cancel, and we are left with mu_s = tan(theta), relating the static friction coefficient to the critical incline angle. Doesn't matter how much mass the object has, doesn't matter whether we do this experiment on Earth or the moon. A full crate and an otherwise-identical empty crate, will have the same critical angle on the same incline surface.

I watched whole video and I understood but Can I aplly this theory to solve Normal and Axial Forces eqs relating pressure & shear stress on an airfoil following to integrate it over the whole surface of the airfoil?

@americanenglishazerbaijan

Im happy to explain. Did you understand the limit part? As the plane gets less inclined, you would expect the downward force to appproach mg right? In fact, when angle is zero, the only component becomes mg. So then you look at your mgcostheta and confirm the observation - as theta becomes closer to zero (as plane gets less inclined) cos of theta is in fact approaching 1, and 1*mg = mg.

Once you have found the Theta angle, the rest follows suit. As the professor says, just go creative, check it out, mistake yes, mistake not, and you will conclude into the right understanding. Creativity, in this case, cannot go wrong but help to find the right angle and the corresponding sinus and cosine.
