**Working of a Hand Lift Machine with Worm Gear and Rack & Pinion Explained!**

In this video, I break down the mechanics of a hand lift machine powered by a worm gear and a rack & pinion system. I’ve simplified the complex process into easy-to-understand steps, using clear illustrations to demonstrate how each component works together. Whether you're a beginner or just curious, this video will help you grasp the fundamentals of this lifting mechanism in no time!

It takes exactly the same amount of force to lift; you just spread it out over more time.

[Rasaiel]

Only this this type of mechanism with worm gears. It does not transfer motion backwards. Use any other type of gear the second you let go the weight will fall and the shift will spin uncontrollably

[doirlyneedauser]

Also don’t forget that the worm gear spins one way, so other gears can’t spin the worm gear

[overflow]

You should do a visualization of how an inertia starter works, they are really cool

[michaelmello]

Beautiful presentation and crystal clear explanation.

[nathanjay]

Work in equals work out. Work equals force times distance. So exerting a small force at great distance means a great force over a small distance. It’s a trade off between distance and force.

[Ahwgsvsb]

The energy referred to as mechanical advantage is transferred to the number of many rotation of the crank, making it simple, instead of lifting you're required just to rotate the crank. 😊

[mik]

It's going to take MORE energy because of the friction of the mechanism. And as one said, it's a matter of time, not force...

[saggyai]

If this was too confusing for you (it was for me) then imagine the math for a single car engine 😭😭😭

[omerelhagahmed]

Could you please clearify why you counted the second 10 cm from the axle to the lifting rod?

[nesensp]

We can use perpendicular bevel gear set and remove the big gear

[Eugetronics]

The worm gear does not rotate in the opposite direction because its efficiency is less than 50%, the calculation does not take into account the efficiency, the calculation is wrong by at least 2 times.

[mrgodly-dredark]

Work gear are 50% efficient so you’ll actually be cranking 20lbs of force 🥲

[darshansingh]

Hi, what kind of software do we use for animation?

[GUNVALKERIE]

All this time i kept calling it the spiral gear

[SiKe_sxt]

why doesn’t the mass re-rotate the gear?

[pianlaw]

besi yang ada geriginya apa nama nya kalau dibeli?

[chalokips]

I have an idea iam gonna make a powerful car jack using the same principal will it work

[logickedmazimoon]

a gear is just a bunch of little levers

[rhranjithkumar]

There's nothing called Mechanical Advantage.
