AI Thread Summary
To graphically represent vectors measured in pounds, the unit of measurement does not affect the drawing process. One can draw the vectors as they would with any other unit, such as meters, by maintaining the same scale. For Vector A at 80 lb and 60 degrees, and Vector B at 120 lb and -45 degrees, the magnitudes can be represented proportionally on a graph. The key is to ensure that all vectors are drawn to scale relative to one another. Ultimately, the graphical representation remains consistent regardless of the measurement unit used.

I understand how to add vectors graphiclly where i am stuck is how to show this one vector on a graph. Vector A = 80 lb at 60 degrees Vector B = 120lb at -45 degrees. the only part that doest make sense is it is in pounds so what do i do for the magnitudes.

Pythagorean theorem
 
what my question is if it were 2m at 30 degrees i would have no problem. Just scale it down and go from their. what is screwing me up is it is in pounds. how do i draw a line with the magnitude of 80 lbs

Provided that all the vectors are in the same unit, it doesn't matter what that unit is. Simply draw a vector with units of pounds as you would if it has units of meters.

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...

Thread 'Egg Drop Challenge! Need ideas for winning designs'

I was thinking using 2 purple mattress samples, and taping them together, I do want other ideas though, the main guidelines are; Must have a volume LESS than 1600 cubic centimeters, and CAN'T exceed 25 cm in ANY direction. Must be LESS than 1 kg. NO parachutes. NO glue or Tape can touch the egg. MUST be able to take egg out in less than 1 minute. Grade A large eggs will be used.
