Here is what our team's field expert Andy lee found out about manipulating the ramp:

(the -'s are just for spacing)
Data set one: An unloaded ramp.

Inches froms pivot point----Static mass required to ----------------------------change posistion(lbs).
----------------------------Slanted--------Balanced

12--------------------------30--------------80
24--------------------------15--------------30
36--------------------------10--------------15
48--------------------------5---------------10

Data set two: Loaded with 260Lbs of robot(105bls), goals(70lbsx2), and balls(black 1lbsx10 each & one big 5lbs)


Inches froms pivot point----Static mass required to ----------------------------change posistion(lbs).
----------------------------Slanted--------Balanced

12--------------------------170--------------80
24--------------------------50---------------30
36--------------------------30---------------15
48--------------------------25---------------10


Force to hold a goal on the ramp while tilted = 10 Lbs
Constant force required to pull the goal up the ramp = 20 lbs
Force to pull the strecher up the ramp = 30lbs

These are all approximate values due to the dynamic nature of the system.
