Calculations Stress

AI Thread Summary

The stress at the upper and lower edges of a girder section profile can be calculated using simple beam theory, which considers the applied load and resulting moment. For a girder with a section modulus (W(b)) of 144 cm³ and an area (A) of 34 cm², the stress values will vary based on the specific loading conditions. A visual representation can aid in understanding the stress distribution along the girder. It is essential to apply the correct formulas to determine the exact stress levels at the fixed end. Understanding these calculations is crucial for ensuring structural integrity.

What is the resulting stress at the upper and lower edge of a section profile with W(b) = 144 cm3 and A = 34 cm² at the fixed end of the girder.

I'm not sure about how it looks like.Can smby pls explain to me (if possible,togther with a picture)

thanx

The stress depends on what load is applied and the resulting moment. Use simple beam theory.

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'

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...

Thread 'Explain this asphalt sheen'

This problem is two parts. The first is to determine what effects are being provided by each of the elements - 1) the window panes; 2) the asphalt surface. My answer to that is The second part of the problem is exactly why you get this affect. And one more spoiler:
