I think I understand. So if it was instead in this position would it then be possible to calculate if it would fail at those points and how?

Hey everybody so I am a student and I am learning about failure analysis. So let's say I have a rigid body that is being kept in this position...there is a moment at A generated by a motor to keep the body in this position, working against the weight of the body itself and small wind force...

Hey guys, so I have to give a 10 minute presentation for my class. I am absolutely terrible at memorizing stuff. Its pretty bad. If I can find an interesting or cool topic I would be able to remember material better. It needs to be about deformation or fracture of a material in terms of micro...

So I am trying to design a beach cleaner machine in Ontario for my project... As part of it I have to research codes and regulations needed to implement it. I can't seem to find any regulations in Canada regarding beach cleaners, are there any?

What are some interesting topics in the field of material fracture and deformation? Maybe a newer area of research?

No i meant length

Based on other parameters how do you calculate the required length of a piston inside the cylinder block of an axial piston pump? What are the relevant equations? I've found many for the required diameter but not the length.

So many good tips lol! Why exactly three piston pumps though?

Yes, I apologize I didnt want to clog up the post with my calculations but I'll try to be clearer next time

Hi Anorlunda! My flow rate is 50 l/min or 0.000833333 m^3/s. I did look look online for a dc pump to meet my specifications but the one I found for that power was like 800 lbs lol...So I thought perhaps I was doing something wrong but I guess for that amount of power it would be quite large...

So I posted yesterday about appropriate pumps for pumping water out of a ballast tank in a manned submersibles at a depth of 1000m. I decided to switch to an axial piston pump. I got that the require pump head is approx. 410 m and the required power input provided by the pump is approx. 18 000W...

Thank you all for your answers. After talking to my professor it seems you're right. I was not supposed to use a centrifugal pump. I feel like such a dummie. What is a example of a piston where it similarly takes in water horizontally and discharges it down perpendicularly like the drawing?

1000m, I am a undergrad student I am not actually building it!

Well we have a compressed air system to make sure there is never a vacuum in the ballast tank. How did you get 114 Bar. But I am having trouble picking a pump. Can the centrifugal pump simply be rotated so it discharges down?
