Is the beam in equilibrium with three forces acting on it?

AI Thread Summary
The discussion confirms that a heavy beam supported by two upward forces and one downward force is in equilibrium. The forces acting on the beam include two upward forces on either side and one downward force in the middle. The correct choice is identified as (C), which states that the resultant force and the resultant turning effects are both zero. Participants agree with this assessment, reinforcing the understanding of equilibrium in the context of forces. The conclusion emphasizes the balance of forces necessary for the beam's stability.

A heavy beam is located on two supports, so that there are 3 forces acting on it.

The beam is in an equilibrium.
There are two forces on top pulling it up and one force pulling it down.
The two forces are on each side and the one on its own on the bottom is in the middle pulling down.

Am I right when I choose C?

(A). All forces are equal in value.
(B). The forces are in one direction and their turning effects are in the opposite direction.
(C). The resultant force is zero and the resultant turning effects are zero.
(D). The total upward force is twice the total downward force.

Im pretty sure I am right but I am just checking.
Thank you!

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'

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...
