Units of BTU, ton's of chillwater, lb mass of steam, are in common use today. I doubt they changed units on Apollo missions to ease calculations, because current crop of engineers were trained in them. This is funny. 40's something female in my engineering class make humorous state, something...

I would say it sent man to the moon. FORTRAN sent man to the moon. A guess; I wasn't directly involved. 60yrs ago, mks was hardly taught in Am universities.

Incoherent systems: it's lost pieces of information like that this and law of tangents wouldn't of happened; amongst other things. Hilarious wracking my brain for want of the lost piece. Most text dont address British Engineer Sys, or Eng Engr Sys. But, ton of chill water used for hvac and...

Thank you. I had completely forgot about this constant. I have thermo txt enroute which will supply plenty problems of lb steam into horsepower. This should help me acclimate to lb mass problems. I had resolved to convert lb to slug since i got numerical equity out of that eq. Which is...

The numerical value of rt does not =left. 1lbf= 1/32slug*32f/s^2. Cancel, not multiply 32. Yields, 1slug*1f/s^2 units which is def of pound force, Steve. You just didn't simplify. Nice try.

I can divide the #'s out, but so what. I want to see 1lbf move 32lbm.

I've pulled this formula inside out. There are only 3 terms. F=ma, a=32.17xxx, i simplified. Even the base definition of lbf=32units of mass/a^2, but is reported as 1lbf. So, i'm not seeing something. If I had, I wouldn't of asked. Take ur time. This is a 45yr problem. I probably don't see a lot...

precisely where is the contradiction? but the product means something, 1lbm*32f/s^2=32lbm*ft/s^2. That is the unit of force! Explain yourself. This is not one pound of force.

Was an enginnering student that lost memory function as result of head injury. Still trying to acquire understanding of thermodynamic coursework which presented problems in BES(British Engineering System), think EES now. I am considering scale design of an aircraft and want to directly work...

Where's the discrepancy?
