Torsion in Spanish is also torsión, maybe Google translated to twist or something related, and isn't a real book, is just a PDF with some exercises that my teacher used as examples, the exercise 43 basically defines torsion but It doesn´t say the units.

Got it, thank you very much for your help

Ok, now I understand the problem, the solution would be θ=2*T*L/(π*G*R^4) where T=(2*0.2)G*m1*m2/(r1+r2)^2 L is the lenght, R the radius and G the shear modulus, but how to calculate θ if the problem doesn't give me G?

I don't Know if this solution to your question is fine T=(2*0.2)G*m1*m2/(r1+r2)^2

Yes, I know

Ok

By the way I do know how the torsion is defined

I am kinda lost, honestly is the hardest question I ever had, right now we were learning about elasticity, Young's modulus and Poisson's modulus. This is the kind of stuff we are learning (is in spanish)...

Homework Statement The torsion balance shown in the figure consists of a 40 cm long bar with lead balls with a diameter of 2 cm on each end. The rod is hanging by a 100 cm long silver thread with a diameter of 0.5 mm. When two bigger lead balls (density = 11.4 g/cm3) with a diameter of 30 cm...
