AI Thread Summary
Vacuum pressure cannot be multiplied in the same manner as hydraulic pressure. While hydraulic systems can amplify force through fluid mechanics, a vacuum represents the absence of pressure, with a maximum limit of zero. Therefore, the only net pressure achievable by creating a vacuum is the ambient pressure acting on the system. This fundamental difference means that the concept of multiplying vacuum pressure does not apply as it does with fluid pressure. Understanding these principles is essential for accurate applications in physics and engineering.

Homework Statement



I know with hydraulic multiplication a small piston can create an increased force upward on a large piston. But if you take the small piston and pull upward on it creating a vacuum. Would the large piston have a multiplied vacuum force pulling it downward.

Perhaps you could explain the configuration you have in mind. If you pull on a hydraulic cylinder, you will push fluid out in front and draw hydraulic fluid in on the back side.

I'm wondering if vacuum pressure can be multiplied in the same way fluid pressure can be multiplied.

No. Vacuum is the absence of pressure. There is a pressure limit for a vaccum: zero. So the greatest net pressure you can create by creating a vacuum is the ambient pressure.

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...
