Calculate Acceleration of Atwood Machine with Friction and Pulley Mass
A block sits on a rough, level surface and is connected by a string that runs over a pulley to a hanging block.
Walk through how to apply Newton's Laws in to each individual object in order to solve for the linear acceleration of each of the blocks. Apply Newtons 2nd Law to each of the blocks in translation (linear motion) and apply the rotational version of the 2nd Law Torque = Inertia x Angular Acceleration to the pulley in order to account for the mass, radius and shape of the pulley.
Setting up a system of three equations and three unknowns we are able to generate an equation for the acceleration of the system.
This problem commonly comes up in introductory physics courses such as high school physics, AP Physics 1, AP Physics C and appears on the JEE and A Level Exams.

Identify Tension & Compression Members in Truss Analysis
zhlédnutí 6KPřed 3 měsíci
A simple no math method to determine whether a beam / member within a truss is under tension or compression. I showed the forces BY the members ON the joints. I know this is not the convention many people follow, but I find it more natural when apply Newton's Second Law to joints when working the Method of Joints to analyze a truss.

Gravitational Force Due to a Long Thin Rod | Infinite Mass Does NOT Yield Infinite Gravity
zhlédnutí 580Před 4 měsíci
Apply Newtons Law of Universal Gravitation as well as some introductory calculus in order to quantify the gravitational force between a point mass and a long thin rod. Taking the limits of this problem to extremes, we will take a look at what would happen if the rod was infinitely long. Interestingly, and counterintuitively enough, we find that even if the rod was infinitely long, and therefore...

cool intro
why can Fr = Fc? can you make any F = another F ?
and...suddenly yoyos make sense
if the semi minor axe (the horizontal one in this case) is larger or smaller, it does not affect the time ? because the time seems to only depends on r1 + r2 over 2, but it seems counter untuitive. If the ellipse is wider, the time should be somehow different, am i wrong ?
the width of the ellipse is dictated by the required velocities at the two burn points.

Why do you keep pointing at nothing up on the corner?
Oh, mountain forks have damping? I guess we're not talking about Rockshox motion control haha.
true.
What's wrong is you not doing the test & just pointing to a picture saying words
what if you put a object like a piece of paper on top of the pipe
KSP players here ?
Sir::: Could this apply to a rocket launch in that for a rocket to go up its first 15 meters it needs to go up at the speed of 17 meters in its first launch second??? and thanks.

Thank you! I have my physics GCSE paper 2 tomorrow and you're the first person to visually show me wtf a virtual image actually is outside of those ray diagrams. Officially better than at least 80% of physics teachers
Very helpful for jee!!!
Why the volume is same on both sides?
volume in must equal volume out. do you mean area? if thats the case, there is a loss in pressure as the fluid gains height.
You say @5:40 "the pressure in the higher velocity region of this flow" and then point to P2=F2/A which is actually the lower velocity region!!! Or you confused me?!?!?!
It's all force/load equilibrium.
I made a car for my daughters science homework. All the kids had to make this and I used an ordinary toy car about 8 inches long and put a mouse trap on top of it with a string attached between the metal wire on the mouse trap and the axle of the car. It didn't work very well. But even with no string attached the movement of the mouse trap wire in a semi circle from the front to the back of car, imparted forward velocity to the car. The car should have moved forward as the wire of the mouse trap moved backwards in a semi circle and then the sudden stop of the wire should have imparted the equal backwards motion to the car but it didn't. The car kept moving forward. I could not figure this out. Still can't. Momentum was not conserved. The whole car and mouse trap together were in a stopped state at the beginning and should have been stopped in almost exactly the same location at the end as the mouse trap triggered. The car should have moved forward and then backwards back to the exact same spot. But the car in real life went all the way across the room. If you did this in outer space and a weight inside a closed space ship is thrown from one side to the other, the space ship will move a bit in the opposite direction and then stop in s slightly different spot because of the center of mass being moved.
Finally, the response to this question after all these years! :) :) Thanks!
nice video, do you explain how these laws can be tied to the inverse square law?
Sure
Is there a similar explainer for when two objects would collide in case of 2D ?
Quite a few of those bubbles were probably air from the melting ice, but I think it was boiling too.
Bro is explaining the methord to shoot body in free fall such as ISS ( INTERNATIONAL SPACE STATION)😅
Sir,I have a problem , its relating to normal force acting on a body , so assuming one situation where two different objects of different masses are placed in contact with each other , now the normal force which would be acting on the first object with mass' M' by the ground will be different and the normal force which would be acting on the second object with mass 'm'will be different but then the normal force which act between the two bodies i. e the masses M and m which are in contact with each other is not different...........could u explain pls ???
I guess, then, if there were a series of magnets held in the ground we could move the car though a road. I guess thats not very different from a car going downhill, being pulled by gravity
14:00 Spoiler::: Newton and Kepler had both stolen all their stuff from a Muslin Scientist known as Al Haytam who had lived around 1000 years ago. In that sense, both Newton and Kepler were frauds, NOT geniuses.!!!!
another white-board scientist, without empirical examples????
Bro i had a doubt how can you project the img on whiteboard of youre blocking it with the whiteboard
Thank you sir i understand it now
Thanks for sharing your knowledge with us. It really helped. I also like how you simply the concept by using sketches and also adding Lofi music alongside as it creates a nice learning environment.
Glad it was helpful!
Not just useless but also highly misguiding and totally wrong! nasa standard!
What if you had a rotating front wheel where the front magnet would be 8 magnets that all face outwards. So it wouldn’t constantly be pulling, it would have a pull and release effect. Also, inside of the 8 arms that the circle of magnets are attached to, there would be bearings inside of each arm that would fall forward from centrifugal force as the circle rotates.
WOW! appreciate your efforts. Thank you so much for explaining the way of doing this math.
Glad it was helpful!
Now if there was an electromagnet in the road, that moves down the road pulling the truck forward the it would work. Like a conveyor belt
Your answer is completely ❌❌❌❌❌❌❌❌❌
So the solution is to remove the beam and have the magnet float in front of the car. Duh!
Is the background music necessary 😩
Its possible... hard plastic rod. And plate the magnet concentrating the energy towards the front of the car. And a plate behind the metal block. Problem solved
This made the equation for springs in series seem so obvious I feel like I could've gotten it myself
Remarquable de clarté, merci!
interesting that it is the same as the inductor combinations
Amazingg!! ❤
Thank you! 😄
Good video. Perhaps reduce or removing background music as it can be distracting.
