why the work done by torque not considered, thanks

I think the answers for Fab and Fac given in the video are incorrect, since their vector sum is not even approximately equal to Fad, which is 294 N. For Fab and Fac, I get 163 N and 191 N, which on vector addition appropriately give SQRT(163^2+191^2+2(163)(191)cos(37 deg +31 deg)) = 294 N.

Thanks sirr

2 equation 2 unknown

THANK YOU!! this video gave me an amazing new insight

Thank you so much

You explained well. Thank you!

Hello I did it on calculator i got a différent answer

Brent, what if the beam is a fixed cantilever?

What the f***

You're calculating the moment, not torque...change the title!

You're amazing

Perfect thank you.

What equation did you use to calculate frictional torque? I couldn't make it out from the video.

Here are my answers (I used t1-Fab t2-Fac and t3-Fad) For t1= 272.25 N T2= 253.98N T3 = 294 N In your final answer, when i check it (all forces on the x-axis should be equal to 0), yours is laying on 1... something. Mine has a closer value to zero.

This is right but the larger unit should always get a 1

This was very helpful, thank you. Was stuck on a similar question for a while before watching the video.

My test is on a few hours but now I know I'm going to get a good grade. Thank you sir.

i don't understand

thank you so much. God bless you.

FAC=1.07FAB

@7:26 actually thats 1.114AC (you made addition mistake of 0.60+0.514=1.114)not 1.156 so that finally Tension in AC=263N

Center of mass for the Y coordinate should be 18/35 or maybe I could be wrong?

Did he switch fab and fac by accident when solving for fac?

I'm confused which one is the area? I don't know where you got the .0125 from

Um. I'm pretty sure it's. Fac = 1.07Fab. Not the other way around. But still, great explanation.

Hi sir... I liked your video. I want to know which tool or the application you have used for and which platform do you use iPad or computer anything? thank you

Well done, much appreciated

May i know what book this is?

😍😍😍

IF YOU LEAD ANYBODY LEAD HIM/HER PROPERLY. MUST BE YOU'RE LOSS. YOU NEED HELP.

What if the 10N was an unknown and a fulcrum point so you have tension unknown and the 10N unknown?

thanks brent, super helpful

This is a good video. Textbooks just keep making this energy topic hard. Thank you so much!!

4:48 why isn't the distance for the woman 6 meters?

excellent video but can you please tell the rule of geometry for that angle part?

Sphere should also have mom. of inertia around its center.

why did not you change the center of mass? While stucking the center of mass changes right?

It's more easy to apply Lamy's law.

Your computations are wrong. you should double check them.

where does the -80fab come from ??

more please

correct but it would be 2.4 kip feet

Sir why did you use sin 30, On 3.5 distance? What if you used cosin 30

hi. I wanna say thank you. this still helps me in 2019.

So on a 500' 65° decline..600plb weight..... Tree to tree guy wire. Using 5/8 braided cable. The tree at the top, the wire is attached 15' up. On the bottom tree, the wire is attached 20' up from the ground. The 600plb object is 8' long and 5+1/2' wide and 3' tall in height. Will be suspended by ropes and three equally spaced tandem pulley trolleys. Where as the top of the 600plb object leading to the bottom of the guy wire will be 9'. How do I know how tight the guy wire needs to be so that the object doesn't hit the ground but ends within 20' of the bottom tree and about 1+1/2' from the ground? Who is the math god?

How lower potential energy leads a molecule to greater stability? If PE goes down doesn't KE goes up so the molecule is less stable?

if I did not go to school or had not learn this already I would have had no idea what was going on...more detailed explanations would be lovely
