I do not have my diagram but it is pretty straight forward : (im on my iphone right now) It is the hydraulic system of rear-end garbage truck. The 1" hose goes to a valve that has 1 inches outputs. We wanted to limit the speed of an hydraulic accessory, so we put a restriction on the output of...

It's been a long time since i had to calculate something like that so i need your help once more. I've got a 38GPM hydraulic pump with 1 inch outlet that goes through a 1" to 5/64" fitting. What would be the GPM out of this reducer? Thanks.

Update: I just checked all the SE references I could find (maybe i skipped a couple) and manage to run the following code. It does crash at some point : Run-time error '-2147467259 (80004005)': Method 'Value' of object 'IJProperty' failed The code allows me to get SummaryInformation : Title...

Hi, I've searched around a bit and could not find what i am looking for. (ref :http://www.eng-tips.com/viewthread.cfm?qid=218229&tmac=fav&val=1,218229) On the long run I want to create a database with all the properties of the files on our server. To do so, i would like to write a program that...

Hi, thanks for all the replies. badbunny: 1) Attached is my FBD. It is pretty much what you recommended. 2) Security factor used will be 4 so that it includes impact. 3) We have cranes built exactly like this one (products that come from Italy), they are used to lift 9000 pounds (lot...

Thanks for the reply, i can't modify the center bracket, and i am aware that the spacers won't help. i rapidly calculated using Beam 2D 69 MPa bending and 10 MPa Shear, then using Von-mises (sigma_bending^2-sigma_bending*sigma_shear+sigma_shear^2)^1/2 gives 75 MPa do you believe this approch...

Hi, I am currently designing a hook that is going to be attached to a lifting beam we just purchased. The beam is rated for 2000 pounds, and we have to lift up to 600 pounds total (2 hooks, therefore 300 pounds per hook). Attached is a drawing of the current design. Because of the thickness...

tygerdawg, i guess you are right. i'll go this way as i have to fix this asap. zekeman, you are right, i do not know everything about "F". i could try to calculate it, but that would probably be a waste of time. Thanks for your help guys.

Hi, Thanks for your reply, I am uncertain of the consistency of the resulting FBD of your equation. I tried to change the axis system (17 degrees, c-clockwise so that the "x" axis is now straight up from center roller 1 to center roller 2.) i tried to sum forces on the new Y axis...

Hi, thanks for the reply, It is impossible to place the two cam rollers so that the F points toward the middle of the two rollers. We might need to add a third roller, but i would really like to be able to calculate if the "mg" is enough to compensate for the horizontal portion of the F...

Hi, thanks for your reply. F1 represents a force applied by the belt system. This system consists of an arm that applies pressure to the roll, and the belts on this system generate the rotation of the shaft (by rotating the roll). R1 is a resulting force as well as R2. I do believe that...

Hi, I am working on a bracket that holds a 150 pounds shaft that can support rolls that weight up to 2500 pounds. The shaft is going to be rolling on the cam at variable speed throughout the process, as the rolls become smaller and lighter. (init speed ~ 20 RPM, end speed( smaller roll, light...
