Thank you for the reply! I actually did end up doing that, converting to SI and checking the results...when they didn't match, I looked up to see if lbf = lb-in/s^2 and it wasn't...like you mentioned, I had to divide my answer by 386 to get the right force. Now it seems the value is low, but I...
The units for mass are in pounds, which I got from Solidworks. The acceleration units are in/s^2. So it does come out to be lb-in/s^2 which is equivalent to lbf. Is that correct or am I wrong there?
Hi everyone,
So I'm working on this project where I have to determine the total force that is being applied to an assembly that is attached to a crank shaft which is in turn attached to a motor that's driving it. I looked up the equations for the acceleration and velocity of a crank shaft (or a...
Thanks for the answer! I decided to perform the analysis in Workbench instead of in Creo and did manage to get some results from your answer.
Thanks again!
Hi
Thanks for the reply. I took a TPI of 4 and etermined the torque required to move the load. I was basically looking for a way to related the RPM and the linear velocity, which I have figured out now.
Also, I'm trying to determine the fail conditions for the L-shaped support holding the lead...
Hi
I'm trying to make a lead screw in Creo which would be used to move a 400lb load linearly along the ground. This would be turned manually using a lever as shown in the pic (not the complete model). I have used a lead screw with a major diameter of 1 1/4 and determined the torque to move...
