AI Thread Summary
Concrete is inherently weak in tension due to its low tensile strength, which can be improved by incorporating materials like steel reinforcement or using fiber-reinforced composites. Welded stainless steel structures may fail from corrosion due to factors such as inadequate passivation, exposure to harsh environments, or poor welding techniques. To address pollution from gaseous impurities during ironmaking, methods like using cleaner technologies and implementing effective filtration systems can be employed. Resources for further information include academic websites and engineering forums. Understanding these concepts is crucial for enhancing material performance and reducing environmental impact.

Hi all in here,

Do you have any idea why concrete is weak when tested in tension and list the steps that can be taken to overcome this? and why might a welded stainless steel structure fail from corrosion?
 
Physics news on Phys.org
any answer??
 
one more question

During ironmaking, some impurities are gaseous,how can pollution from these be reduced?

that sounds more like a demand than a question and that question sounds more like chemistry than physics
 
could you give me any location to looking for answers,any website that I find everything regarding my questions.

thanks
 

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...
