    Rolling Separation
AI Thread Summary
To calculate roller separation for elastic recovery in rolling mills, first determine the elastic strain using the yield strength of 60 MPa and the modulus of elasticity of 124 GPa. This involves calculating the elastic deformation that occurs when reducing the metal plate to a thickness of 4 cm. The roller separation must be set less than the final thickness to account for the elastic recovery after rolling. Accurate calculations ensure that the material achieves the desired thickness while accommodating its elastic properties. Understanding these principles is crucial for effective rolling mill operations.

No idea where to start with this one, any help is much appreciated...

"A metal plate needs to be reduced to a thickness of 4 cm by involving a rolling mill. After rolling, the elastic properties of the material cause the plate to regain some thickness. Calculate the needed separation between the two rollers when the yield strength of the material after plastic deformation is 60MPa and modulus of elasticity is 124GPa."

Calcuate the elastic strain from the yield stength and elastic modulus.

Then calculate the amount of elastic deformation (recovery) in 4 cm. The separation has to be less than final thickness because the elastic deformation is recovered.
 
Great, thank you.
 

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
