Thanks John. I appreciate your thoughts and yes, the parts still needs to be related to position of the holes.
Really, to clarify, my only concern with the drawing is that the co-ordinate dimensions do not run parallel and perpendicular to the reference frame established by the datums A-B,C...
Hi everyone and thanks for taking the time to help out. I think my question is fairly simple. Here at work we are dimensioning a moderately complex part and want to apply some tolerances to the position of a few mounting holes. You will see that we've defined a datum "A-B" (Aside: I need to...
Hi all and thanks for taking the time to consider my question.
I have a hollow pipe that is cantilevered at its base with a bending load at its top. I would like to find the displacement of its centre of gravity. The problem is that the CoG is in mid air at approx the centre of the pipe. Is...
Thanks BigInch, some great advice there. I do have a ultrasonic flowmeter available to me so I can use that to verify whatever flow reading I get. For various reasons I must also perform testing at the discharge outlet. I have a few follow up questions for you if you wouldn't mind clarifying a...
Hi all and thanks in advance for the help. I have the following query regarding taking measurements from a discharge pipe using a pitot tube.
There is an pipe outlet at the bottom of a pool of water which is 12" deep. I am trying to establish the volume flow rate out of this outlet using a...

The torque requirement would be minimal. This is a very low load application being driven by finger force in order to index an inspection fixture forward and back under a scope using a downward force only (lateral forces tend to knock the inspection fixture out of the field of view of the...
Thanks for your reply Kyle. I think what I need to focus on here is a mechanism to disengage the rack and pinion mechanism. I plan on looking at a system using dogs mounted on the shaft to do this. Any more advice would be great.
Thanks again.
Hi folks, I have a little design job that involves using a vertical reciprocating motion (i.e. a finger repeatedly pushing a button) to move a lead screw forwards incrementally. Once the carriage that is mounted on the lead screw is at it limit it needs to be returned. The picture at the link...
Hi there everyone. I have what I think should be a straight forward question. I'm trying to model the radiative heat flux leaving a surface. The following is the standard solution to the problem.
P(out) = ??A(Tsurface)^4 (1)
P(in) = ??A(Tenvironment)^4...
Hello all! What I want to do might well be impossible to do with VBA but I hope I’ll be proved wrong here!
What I need to do is copy/paste a load of scientific data from excel cells into an explorer web browser window which is set up for the data (small text box style windows for inputting data...
