Student on team #192, Gunn Robotics Team, from Henry M. Gunn Senior High School. In Reply to: Weight needed to tilt bridge... Posted by Angelique on 1/26/2001 5:27 PM EST: 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. |
