Hydrostatics - submerged lamina

AI Thread Summary
To calculate the depth of the center of pressure for a submerged triangular lamina, the centroid is first determined to be 2.5m from the water surface. The center of pressure will be located below this centroid. The user expresses uncertainty about the next steps in the calculation and indicates that vital information is missing from the problem statement. Additional guidance is sought to proceed with the solution. Understanding the relationship between the centroid and center of pressure is crucial for solving this hydrostatics problem.

Homework Statement


Calculate the depth below the water surface of the centre of pressure of the water pressure acting on the submerged triangular lamina, height 3m, base 2m and located at a depth of 1m below the surface.

Homework Equations


not entirely sure

The Attempt at a Solution



I found the centroid location at 2.5m from the surface, c= (2)(3)^3/36.. now i have no clue what to do. any tips?, I now that the center of pressure must be below this point

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...
