AI Thread Summary
To compress an iron block by 0.16%, a specific pressure or stress is required, which can be calculated using the relationship between stress and strain. Stress is defined as force divided by the cross-sectional area (csa), while strain is the change in length divided by the original length. Young's modulus for iron is essential for this calculation, as it relates stress to strain. The discussion emphasizes the need to reference Young's modulus values to determine the exact pressure in N/m². Understanding these relationships is crucial for accurately calculating the required pressure.

How much pressure is needed to compress the volume of an iron block by 0.16 \%? Express your answer in {\rm{N/m}}^2.

I know pressure is the same as stress, and that stress is force/csa. Could someone point me in the right direction.

Look up the relation between stress and strain.

Also, you will need the value of Young's modulus for iron.
 
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...
