AI Thread Summary
The discussion centers on calculating stresses related to bending and compression in a beam, specifically at points A and B. The user is seeking guidance on the appropriate equations to apply for these calculations. A suggested equation for bending stress of a curved beam is provided, although the user expresses uncertainty about its accuracy. The conversation highlights the need for clarity on the neutral axis's position in stress calculations. Accurate calculations are essential for understanding the mechanical behavior of the beam under stress.

All info is in the link above


I am stuck on the problem for the longest time.

What I do know is that bending will be at point B and compression at point A.

I just don't know how to calculate the stresses at those points

any advice will help.

Well I can't recall the exact equation at the moment, but you need to look up the equation for bending stress of a curved beam.


EDIT: If I remember the equation correctly (I might be wrong but it looks something like this)

\sigma_b = \frac{M}{AR}[1+\frac{1}{m}\frac{y}{r+y}]

where m is constant for a particular cross-section

does that equation look familiar or do you use the equation that accounts for the position of the neutral axis?

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 hanged mass'

Thread 'A cylinder connected to a hanged 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...
