Calculating Bulk and Shear Modulus with Young's Modulus and Poisson's Ratio

AI Thread Summary
To calculate the Bulk modulus (K) and shear modulus (G) from Young's modulus (E) and Poisson's ratio (ν), the formulas K = E / [3(1 - 2ν)] and G = E / [2(1 + ν)] can be used. Given a Young's modulus of 250 GN/m² and a Poisson's ratio of 0.32, the Bulk modulus and shear modulus can be derived using these equations. The discussion also references helpful resources for understanding Poisson's ratio and bulk modulus. Overall, the focus is on applying these formulas to complete the coursework assignment. Understanding these concepts is essential for accurate calculations in material science.

Hi Can any please help:

My course work is asking for me to calculate the Bulk modulus and shear modulus for a material that has a Young's modulus of elasticity of 250GN m-2 and a Poisson's ratio of 0.32?

Any help will be great thanks

Does your course work include an explanation of what Poisson's ratio represents?

Here is a refresher:

There's also an article on bulk modulus:

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'

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...
