AI Thread Summary
The discussion focuses on calculating the horizontal forces exerted by two hinges on a door that is 1.00m wide, 2.5m high, and weighs 250N. Each hinge, positioned 0.5m from the top and bottom, supports half the door's weight. It is noted that the horizontal components of the forces from both hinges must sum to zero. The conversation includes a hint about taking moments around the door's center to analyze the forces. Understanding these principles is crucial for accurately determining the hinge forces on the door.

1. A door 1.00m wide and 2.5m high weighs 250N and is supported by two hinges, one 0.5m from the top and the other 0.5m from the bottom. Each hinge supports half the total weight of the door. Assuming that the door's center of gravity is at its center, find the horizontal components of force exerted on the door by each hinge.



2. \suma = \sumc



3. Taking moments about the middle of the door but unsure of the values of the equation

Hi Harrison! :smile:

Hint: the horizontal components of the forces on the two hinges will add to zero. :smile:
 
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...
