24-262 Stress Analysis – 2012 Design Project
How our mechanism works:
Our lifter is made up of a support that rises up directly from the clamp
base and a rigid i-beam that spans from the base, through the right hole,
to right near the target weight. At the end of the i-beam a 72 oz-in torque
servo is attached. To the servo is attached a rod with a counter-weight on
one end and a notch on the other. The counter-weight serves to aid the
servo in the lifting of the notch. The notch hooks on to the target weight
and is able to lift it just over 2 inches.
Interesting and original features:
-Access through smaller window
-Direct path from base to weight
-Base is a stable central supporting beam instead of a box
-One main i-beam instead of a truss structure
Percent of servo torque used: 70.83%
Theoretical lift: 4.23 in.
