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 'Collision of a bullet on a rod-string system: query'

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

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...
