Hey your comment worked!

I agree!! The only time I was allowed to play with Lego in school was in 9th grade. We were given a box with Lego Technics and instructed to build the whole model as fast as possible. It was really fun to do with your friends and I'll always cherish building Legos with my friends in school :') our teachers were awesome.

Hell yeah Fred

I'm guessing you learned principles 5, 6 and 7 through practical experience?

Or perhaps through another video platform than RU-vid

That is absolutely an absolutely magical memory/ life lesson, thank you for sharing that. My daughter hasn't even started kindergarten, but believe it or not shows tremendous curiosity, and true careful study (or wonder) for little mechanical principles and examples like this. Maybe one day I can explain mechanical theory to her, using something similar to the bar-stool method your dad used to explain to you, all those years ago.

That's the best part about basic physics stuff, so much can be learned just by fiddling around. With a little bit of explanation added in and suddenly you can hear why what you see happens or vice versa, it's amazing for comprehension.

That's wholesome, thank you for sharing :)

That was so sweet, it brought a tear to my eye. I strive to be that kind-of dad.

As a software person: Yeah. I'D have no idea how to make most of these. I'd just use multiple motors, servos and gearboxes controlled by software and relays :D

@@IanDresarie I'd just virtualize it in lego software

@@IanDresarie I think the hardest part is actually knowing all of the different possibilties- it's one thing to be able to name all of the simple machines, but it's a totally different thing to know the catalog of different linkages used in modern mechanical engineering and the best and most simple ways to transform and transfer forces

@@messedupmayhem That's the thing; virtualization uses continuous power, and the software construct cannot do any RL work. A machine, the parts are made once (limited energy input), the assembly is made once, and the machine can do work over and over again. Virtualization is not an end in itself; it is just an intellectual tool for making real things. That's all that CAD/CAM is for anyway.

He would probably burned for witchcraft.

0:59 this reminds me of a piston engine

Well the issue there is almost of these are just variations of the sams idea: changing one kind of motion into another or transporting it. They're good for a specific purpose but not much outside of that. Like the most important bit to people who didn't know about this is simply the gears and their mechanical advantage. Just hook a few gears up to something you can make spin like a windmill or water wheel, and now you've got a drive for your machine. Use it to grind grain or spin a saw blade or pump bellows. The leap not explained here that would be huge is the power source. Not needing to rely on the wind or water for drive was what made the steam power huge. We already had all the gears and pulleys for a long time, but being able to power them wherever we wanted and scale up that power in was the part that made the industrial revolution happen.

What would some of the great minds of antiquity have thought? The great Greek philosophers and thinkers they would like took your bong from you and said mind blown and then took a hit

Sort of, but not really. Some of those machines do nothing but spin and create extra work for the motor, ultimately resulting in a significant loss of work. In a Rube Goldberg, each segment of the machine performs a specific task which ends with the start of a new segment while ultimately striving to achieve a very simple function in a convoluted way. This machine performs a simple task (spin the Viking angel figure) but wastes a lot of work on segments that don't contribute to the ultimate goal. Frankly, I'm kind of surprised the motor didn't stall.

rather hard on the shaft 😏 i apologize

@@handletemplate Here's a wrench🔧. Now bonk yourself.

My sister like 5. Slider-Crank linkage

Yes, many of these linkages have excessive friction, wear and tear as their drawbacks, which means that in practical application they must _always_ be offset by the additional degrees of freedom of movement they offer. This is why I expected some of the movement to be directed backward to actuate (move about) the fixtures of some of these linkages. So I am rather disappointed. He missed an opportunity to demonstrate just why these solutions exist.

Well Slider - crank linkage is used on plenty of revolutionary dildo machines 🤣🤣

I'd be happy to explain the practical uses of each mechanism and its real-life application examples. Schmidt coupling - A Schmidt coupling is used to connect two rotating shafts that are misaligned. It is commonly used in machinery and vehicles to transmit torque from the engine to the wheels or other moving parts. Constant-velocity joint (CV joint) - A CV joint is used to transfer power from the engine to the wheels in a front-wheel-drive vehicle. It allows the wheels to move up and down while maintaining a constant speed. Universal joint - A universal joint is used to connect two shafts that are not in line with each other. It is commonly used in drive shafts to transmit power from the engine to the wheels. Bevel gears - Bevel gears are used to transmit power between two intersecting shafts. They are commonly used in differentials and other gearboxes. Slider-crank linkage - A slider-crank linkage is used to convert rotary motion into reciprocating motion. It is commonly used in engines to convert the rotation of the crankshaft into the up-and-down motion of the pistons. Sun and planet gear - A sun and planet gear is used to transmit torque between two shafts that are not in line with each other. It is commonly used in gearboxes and automatic transmissions. Scotch Yoke - A Scotch yoke is used to convert rotary motion into reciprocating motion. It is commonly used in engines to convert the rotation of the crankshaft into the back-and-forth motion of a piston. Chebyshev Lambda Linkage - A Chebyshev Lambda linkage is used to convert rotary motion into reciprocating motion. It is commonly used in engines to convert the rotation of the crankshaft into the up-and-down motion of the pistons. Chain drive - A chain drive is used to transmit power between two shafts that are not in line with each other. It is commonly used in motorcycles, bicycles, and other machinery. Belt drive - A belt drive is used to transmit power between two shafts that are not in line with each other. It is commonly used in machinery, vehicles, and other equipment. Constant-mesh gearbox - A constant-mesh gearbox is used to transmit power from the engine to the wheels in a vehicle. It allows the driver to select different gear ratios to match the speed and torque requirements of the vehicle. Oscillating direction changer - An oscillating direction changer is used to change the direction of motion of a rotating shaft. It is commonly used in machinery to change the direction of motion of a tool or other moving part. Torque limiter - A torque limiter is used to protect machinery from damage caused by excessive torque. It is commonly used in conveyor systems, industrial equipment, and other machinery. Winch - A winch is used to lift or pull heavy loads. It is commonly used in construction, mining, and other industries. Rack and pinion - A rack and pinion is used to convert rotary motion into linear motion. It is commonly used in steering systems to allow the driver to control the direction of a vehicle. Offset gears - Offset gears are used to transmit power between two intersecting shafts that are not in line with each other. They are commonly used in gearboxes and other machinery. Uni-directional drive - A uni-directional drive is used to transmit power in one direction only. It is commonly used in machinery and other equipment to prevent backflow or reverse motion. Camshaft - A camshaft is used to control the opening and closing of engine valves. It is commonly used in engines to regulate the intake and exhaust of air and fuel to the cylinders. Intermittent mechanism - An intermittent mechanism is used to control the timing of the movement of a rotating shaft. It is commonly used in machinery to stop and start the movement of a tool or other moving part. Worm gear - A worm gear is used to transmit power between two shafts that are at a right angle to each other. It is commonly used in machinery and equipment to reduce the speed and increase the torque of a rotating shaft.
