I meant the mass of the bar on the right side of the center of mass

The mass of the bar on the right side?

They cancel out at the center of mass?

I see now that it is (15 + x ) / 2 - x

is it: 15 - (15+x)/2 ?

I really don't know

isn't the center of mass exactly in the middle?

the bar is 15cm on the right side. The mass is 3 grams / cm. So 45 grams.

Homework Statement The bar has a mass of 3 grams/cm. When a mass of 15 grams is hung on the left side, the system is balanced. Calculate the length of the bar. Homework Equations F1*r1 = F2*r2 The Attempt at a Solution I thought that the moment on the left should be equal to the moment at the...

The rope is indeed not massless. Thank you very much for your help.

I meant to say that the rope has mass

It doesn't state that the rope is massless, so I guess not.

If T1 = T3 then m1 = m3 This means that m2 = 2*m1 ? But now I face another problem because according to my teacher, the answer should have been: m2 < 2*m1

So T1 + T3 - m2*g = 0 ? m1*g + m3*g = m2*g m1 + m3 = m2 ? Am I approaching this problem the right way now? I found out that I made a mistake in the possible answers. It should be: mblock2 = 2*mblock1 mblock2 > 2*mblock1 mblock2 < 2*mblock1

Homework Statement Find the relation between the mass of block 1 and the mass of block 2. Assume that the pullies are massless and frictionless and that the rope is inelastic. All masses are unknown. Possible answers: mblock2 = mblock1[/B] mblock2 > mblock1...
