Simple Machines for Engineers | IMA AMA and % Efficiency

Take a look at how we define ideal mechanical advantage in simple machines, actual mechanical advantage as well as how each type of simple machine produces that mechanical advantage. Additionally we will look at how to calculate percent efficiency in a simple machine.
Ultimately simple machines boil down to the relationship between input work and output work. This is because an input force, also known as effort force acts over an input distance producing work. As a result of the conservation of energy an output force or resistance occurs at the other end of the simple machine over some output distance.
In a simple machine the input and output works are equal unless the simple machine is not 100% efficient. We will see how to calculate percent efficiency in a simple machine in this video.
Simple machines are typically covered in introductory physics and engineering courses. Project Lead the Way Principles of Engineering ( PLTW POE ) being a common setting at the high school level.

This video is extremely underrated. Great review for my MechE Internship interview I have tomorrow. Thank you so much!

Glad it was helpful!

Your penmanship is perfect. What simple machine is a rubber band.

[@INTEGRALPHYSICS]

A rubber band is a spring. Springs arent simple machines, they store energy then release it where as a simple machine conserves energy but multiplies force.

Good video 👏

Thanks 😁

i think, if in closed systems, energy is conserved..... im just saying... correct me if im wrong

[@INTEGRALPHYSICS]

Ideally, yes. The energy that goes into a simple machine should come out. The job of a simple machine being to exchange force for displacement (or vice versa).
In reality, some of the energy put into a simple machine is lost to friction. As a result we have to differentiate between Ideal and Actual Mechanical Advantage.

The background music is really pissing me off.

Happy to help, however: I'm over 40, I have absolutely no idea what those emojis mean.
