AI Thread Summary
The discussion revolves around calculating the force needed to support an object using a hydraulic press. The first part of the problem was successfully solved using the formula F1/A1 = F2/A2, which relates force and area. The second part requires incorporating the height of the object and the density of the oil in the hydraulic system. It was clarified that the total force must account for both the weight of the object and the mass of the oil column at the specified height. The final approach involves calculating the pressure needed to support the combined weight at the given height.

Ok, it's a two part question, i did the first part with no problem, which is how much force it takes to hold an object on the other end up, knowing the diameters and the mass of the object, i just used F1/A1 = F2/A2. Now, the 2nd part asks how much force is needed to support the object at a certain height. I have no idea how to put height into it. Anyone know? thanks in advance.

Tell me if u need me to post the exact problem

Post the exact problem. Part 2 doesn't seem to make sense.
 
um wow, i just realized from typing the problem out, i been missing some given data, about the density of the oil in the lift. um, i think i got it now, you just calculated the mass that need to be lifted including the mass of the oil in the cylinder of the height needed to lift right?
 
I think you've got it. Let me restate it. Piston 1 is at height 0; piston 2 is at height H. The pressure at height 0 must support the column of oil (of height H) plus the added weight. Then apply F1/A1 = Pressureh=0.
 
alright, thanks
 

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 'Collision of a bullet on a rod-string system: query'

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

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...
