Question

Moments Hw

Answer 1

This is a different problem, but I just want to know if I'm right. Would I add up all the numbers on the left side, and F would be the number that makes the right side added together equal to the left side?

Answer 2

I never exactly passed physics
but logic tells me that the position of the weights has an affect on the balance. like the closer it is to the middle affects the tilting less or something

Answer 3

Oh yeah, that is true. I'll look into that thanks Angle

Answer 5

you just have to do
125+375+1000=x+200+100
solve for x

Answer 6

i-
...
what did I just say snowflake?

Answer 7

lol, sorry, it's just that your explanation confused me

Answer 8

the distance of the weight away from the center/lever affects the amount of force

Answer 9

and that sounds so complex\(\color{#0cbb34}{\text{Originally Posted by}}\) @Angle

\(\color{#0cbb34}{\text{End of Quote}}\)

easier to just say the opposite sides of the thing equal each other

Answer 10

lol

Answer 11

nonono you dont understand

something like this can be balanced because of the distance away from the middle

Answer 12

oof, nvmd then lmao

Answer 13

Yeah that's what I initially thought snowflake

oof, we're both dum dum's then lol

Answer 15

Weight x Distance from center = Weight x Distance from center
seems to be the formula

Answer 16

i learned something today xD

Answer 17

my logic skills tell me that adding something should be ok
so let's do
\((125*5)+(375*4)+(1000*1)=(200*1)+(100*3)+(x*5)\)
as you can see, I have decided to assign each position a unit

Answer 18

I see what you are trying to do, I can try that first

Answer 19

I got 525 using your formula, which kinda does seem logical but I'm not 100% sure

Answer 20

I got the same

Answer 21

I can't promise you that it's correct (see above: didn't pass physics)
but it is definitely going to be more correct than what you or snowflake were trying

Answer 22

Yeah lol, thanks for helping us. Btw it's principles of engineering but it is similar to physics

Answer 23

well good luck with your class... google is your friend

Answer 25

Thanks, ohh yeah that's true, I could search this problem up but I'm pretty sure my teacher made this assignment himself so I doubt it would be on google. Or I could just research how to do a similar problem...

Answer 26

yes yes
for example, for this problem I searched: "weight distribution on fulcrum formula" which gave the Weight x Distance from center = Weight x Distance from center
formula that we used

Answer 27

so I recommend googling the main idea / look for the formula rather than the exact question

Answer 28

Yeah I do see that when I search it up. Thanks for the tips

Answer 29

just to slightly elaborate on what was said before - in terms of physics, you're looking for the torque exerted at each point, which is torque = rFsin(theta)

in this case, theta is the angle between the force and the axis, which is 90 degrees, so it basically does reduce down to distance * weight as mentioned before
