yes it's .8

>yes it's .8
incorrect

>>55758284
It might be 1, if it's the torque that the axle has to endure.

>>55758284
4.0cm nigga

Have you tried entering 0.20? Mastering Physics is fucking shit for interpreting answers. I haven't done physics in a while but that's what I got too. Net force is 10 Newtons since the 20N force opposes the 30N force. Moment arm is the radius, so 2.0 cm. So net torque is 0.02*10 = 0.20.

>>55758394
Oh shit, nigga. Your net torque is in the clockwise direction. That means your answer should be negative since torque is a vector.

Clearly it's over 9000

-0.2

>>55758465
Yes, exactly.

>>55758284
Please tell me you didn't pay money to get in mastering physics

That would be the brain dead thing

>>55758468
Well, -0.20, since it asks for two significant digits.

>>55758483
Lots of physics courses require it for the assignment portion. Otherwise you give up 10-20% of your grade.

>>55758504
Well of course you need to do your homework but that you have to PAY to do it is absolute bull

Fucking Pearson

>>55758522
It's a fucking scam alright, but at least they let you buy the access code separately. Surprised they don't make you buy the textbook, too.

>>55758532
It's 100 bucks you basically are

Ah I remember masteringphysics. All those fucking sleepless nights from doing electromeganetic physics and the fucking program not accepting my fucking free body diagrams.

>>55758556
Shit, it was only about $50 when I took physics, and that was about 3-4 years ago.

The biggest scam was clickers. You'd have to buy this $30 plastic piece of shit that looks like an invalid bed remote from the 90's to answer pop quiz questions in class. "You'll be able to use them in all your subsequent classes", they said. Nope.

>>55758567
>Now make the length of the arrow correspond to the force
"No"

>>55758578
It's all such a scam really just surreal

.2 Nm nigger

Torque = (Net Force)(distance) = (F1cos0-F2cos0)(radius)
=(30-20)(4/(2/100)) Nm
=.2 Nm

>>55758578
Fuck, I hated that thing so much. Never even used it once. It represents everything I hate about undergrad.

my course had the option, and if you didn't take it, the weight would be added onto the final

fuck you Wiley

I had to use webassign for my diff eq class. Costed something like $150 to get a log in and included the textbook needed for the class for "free." I could only it view when logged into the site and expired about 3 months later.

The worst part was I had a pdf of the textbook from a friend and there was no way to sign up for that shit website without paying for the "free" textbook.

>>55758632
As I mentioned, torque is a vector so he has to indicate the counterclockwise direction with a negative sign.

>>55758950
Oops, I meant clockwise direction.

Ah yes you are right, I'm getting dumb
