What Is the Tension in Each Pedestal of a Diving Board?

AI Thread Summary
The discussion revolves around calculating the tension in two pedestals supporting a diving board with a diver on it. The diver weighs 582 N, and the board itself weighs 142 N, with the pedestals spaced 1.55 m apart. The user has started by drawing a body diagram but is unsure how to proceed with torque calculations. They are advised to select one pedestal as the point of rotation and balance the clockwise and counterclockwise torques to find the tensions. This approach will help in determining the forces acting on the board effectively.

Homework Statement



A diver of weight 582 N stands at the end of a uniform 4.48-m diving board of weight 142N The board is attached by two pedestals 1.55 m apart. Find the tension in each of the two pedestals.

Homework Equations



Torque= force x distance
Torque = Rotational Interia x angular acceleration or I=mr^2
Friction= usN

The Attempt at a Solution



So far I just draw a body diagram. I got no x-component based on the fact there no force and for vertical component is gravity facing down. I don't know what else to include, plus how can I find a torque.

Help me if you can, thanks.

You can pick any point as the point of rotation (since it is not rotating), so pick the point of contact of one of the pedestals.
set up an equation balancing all "CW" torques with all "CCW" torques. Just imaging each applied force trying to rotate the board around that point of contact.
 

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...
