It might look simpler with the tangent but it is kind of obscure and you have to deal with several angles! I prefer to decompose the normal forces and use equilibrium equations

Thanks again for always making everything simpler💯. I'd be lost in my course without your videos

Then what is the purpose of using Wedge when applied force comes greater than weight...in this case we got mechanical advantage less than 1..ie mechanical disadvantage
@MichelvanBiezen Жыл бұрын
The mechanical advantage is that you can lift an object with a force that is smaller than the weight of the object. The efficiency however is less than 1 (which is typically the case in the real world).

This seems to dispel the idea of the inclined plane as a mechanical advantage. You see, it has long been said that F is lower than W when pushing a weight up a ramp.....that's the "advantage" part. In this video, the person shows that F is actually greater than W, proving that their is a mechanical disadvantage to using an inclined plane to move a weight. That goes for screws as well.

I also noticed it, what could be wrong because all forces are placed correctly. F force should be less than weight W.
@VirenderKumar-ss9qk3 жыл бұрын
It's correct as there is friction as well.implying F needs to work against both W and Fr.

what happens if the block being lifted by the wedge is fixed? how do you calculate the force applied from the wedge on the block as the wedge is forced in? i understand this would be a compressive force, deforming both the block and the wedge (one more than the other, depending on the materials).
@MichelvanBiezen10 ай бұрын
As you indicated, it would depend on the Young's modulus of the material, the cross sectional area of the material and the height of the block.

why we are not considering the reaction on both sides of the wedge
@vijayakumark64156 жыл бұрын
Is it because the block looses the connection from the right side

what if the weight is tilted in an angle
@MichelvanBiezen3 жыл бұрын
Once the wedge is pushed underneath the object, the object will automatically begin to tilt due to the shape of the wedge.
