This video goes over the different ways to calculate the mechanical advantage of a simple machine. The example goes over an example using a lever as the simple machine.
Whoa !!! thanks man ...I was just trying to understand this all semester and it's my final exam tmrw and I had just wasted all day for this stupid lesson but now I understand how simple it is 😅😅
@@MrLeavittScience oh wow over 6 years ago - didn't notice the date. Some things are timeless, like mutton chops. I like but they are only reserved for the Bold.
Ok I think I get it. If I wanted a mechanical advantage of 5, and I have a 6m stick, and I push down on one end of the stick with 10N of force, then I need to place the fulcrum at the 4.8m mark, and the result will be that I lift 50N of force. I guess distance is involved too but not sure how-pushing a lever down results in rotational angle and that's where I get lost.
My suggestion is to fill in the formula, obey the order of operations, hold on, and follow your mathematical heart. It takes some practice...which brings confidence...which is what you need. X means multiply, / means divide. ALGEBRA FOR THE WIN!!
someone help! If the load is five time heavier then effort but the fulcrum is placed 1 meter away from the load (on a four meter plank) the ratio from effort arm and effort length is different then force load and force effort, so wouldnt the mechanical advantage change? like say i the video the bigger guy was 50 pounds and the small was 10, but the fulcrum was placed one meter away from the big guy, so the ratios would be 1:5 and 1:4 and the MA would be different.
Chloe Seljak if you change the load to a ratio of 5:1 then the distance in order to balance would be the same. but when you change that distance, yes your MA will also change. I should have been more clear on the whole need to balance the lever thing thang.
make sure to balance your lever in case you make it very big. i can stand up a big wooden pillar into the air without effort to do so or a pillar of stone for that matter. just learn the power of balance and anythings possible. by the way you can get free energy from this as well if you do some mechanical switching. not that you are clever enough to figure this out anyway. there will be a displacement of linear distance then but that is of very low energy.
Thanks. My daughter missed this teaching (in Grade 8), and I’ve watched 3 demos, and yours is clearest. So thanks! And boy would I have loved to to hang out with Bowie, too - albeit not in his drugs and sexcapades days! But he was one of the most insightful and intelligent people out there, and a true artist and legend. He was often far ahead of his time - such as when he took MTV to task for not playing Black artists, or when he suggested the evils to come from social media and the digital world. At least I got the chance to see him live 3 times. But never enough. There’s nobody else out there like him, or like Prince, another true artist that we’ve lost. So far, my hope is with Bruno Mars, the Weekend, and maybe Harry Styles to fill some of what the music world has lost. Who are you seeing with that potential?
You are not stupid but not understanding,That's a huge difference,That's why I'm also watching this video and it doesn't mean I'm stupid. Love yourself,believe in yourself and respect your self.
@@MrLeavittScience They're asking for the resistance distance. If I can figure out the equation I can solve the problem. I just don't know how to rearrange the equation. And the other one is asking for effort distance. I understand how to do the mechanical advantage ones just not how to rearrange ronfind the other things. My teacher described stuff as output force/input force = input distance/output distance. I'm just having trouble figuring out what to fill in.
@@atlas3231 I hear you. If I understand your teacher right then we have the same formulas, just said differently. Let me try to clarify things for you. Output Force = Load Force Input Force = Effort Force. Input Distance = Effort Arm (or distance from the input/effort to the fulcrum) Output Distance = Load Arm (or distance from the output/load to the fulcrum) At around the 4:00 minute mark of my video I have my formulas and a drawing that is exactly what your teacher told you. I can understand how you may be a bit more confused while watching this video because the language sounds so different. Maybe this can help you.
Freshmans in high school where you at? My science teacher is... I don't get anything he teaches and I got the worst test grade of my life in his class.
