So I've gotten an answer, but my percent error was huge, which is why I want to make sure that I did it right. Can someone do this real quick and tell me what they get?

net torque caused by the 10 gram mass ?

(.010)(9.8)(.48) = .047 N-m

I get x = 2.4 cm to balance the system using the 200 gram mass. - January 4th 2009, 02:07 PMIntrusion
Thanks, that's what I got. I guess it's meant to have a huge percent error. What could be the cause of a 70% error? (the "actual" value should have been 8m with a 200 kg mass)

Since 200 is 10 x 20

It stands to reason that 48/20 = x

Thus 2.4 cm

I see it's already been answered, sorry for excessive posting. - January 4th 2009, 02:11 PMMush

Alright, I'll have to enlighten my teacher then and let him know his "actual" answer is wrong. Thanks!
