Static Equilibrium of pedestals

AI Thread Summary
The discussion focuses on a physics problem involving static equilibrium of a diving board supported by two pedestals. A diver weighing 730 N stands at the end of a 5 m board, with pedestals spaced 1.5 m apart. The equations for the sum of forces in the vertical direction are established, leading to two equations involving the forces from the left and right pedestals. Participants confirm that the approach is correct, as it provides two equations with two unknowns, allowing for the calculation of the forces. The conversation emphasizes the importance of correctly applying static equilibrium principles to solve for the forces acting on the board.

Homework Statement


A diver of weight 730 N stands at the end of a diving board of length L = 5 m and negligible mass. The board is fixed to two pedestals separated by distance d = 1.5 m.

What are the magnitude and direction of the force on the board from the left pedestal? (Include the sign. Take upward to be positive.)


Homework Equations


I think that it's this..

sum of forces in the y direction = 0

force of left pedestal = Fl
force of right pedestal = Fr
force of diver = mg = 730N



The Attempt at a Solution



-Fl + Fr - mg = 0
3.5Fr(mg) - (0)mg = 5Fl(mg)

is this on the right track?

Looks good! You have 2 equations with 2 unknowns so you can find the answer.
 
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...
