    Designing Gears
Click For Summary
The project involves creating a human-powered vehicle equipped with a claw capable of gripping various objects, including those weighing up to 2.2 lbs. The claw design must incorporate pulleys, levers, or gears, with a suggestion to use a scissor-like mechanism for functionality. Participants in the discussion are encouraged to brainstorm and share design ideas, emphasizing the importance of prototyping. The conversation highlights collaboration and the iterative nature of design. Overall, the focus is on developing an effective and functional claw mechanism.

Ok for this project I'm supposed to build a vehicle that is human powered (the easy part). the hard part is, I have to make a claw that will be able to grab things like erasers, balls, and a bucket with a 2.2 lb weight in it. It will also have to be able to grab a ball from a stool and place it on the ground and visa versa.

Can anyone help me on the design onf the claw? IT has to be made out of pullys levers and gears. Actually just 2 of the 3. Any input would be greatly appreciated :smile:
 
Physics news on Phys.org
use the idea of scissors where the blade is the claw, we can't design the whole thing fo you now can we.
 
hey... th ats actually a really good idea! lol thanks for the tip.

i'll try to devise some prototypes
 

Thread 'Does acceleration affect impact energy vs constant velocity?'

I do not have a good working knowledge of physics yet. I tried to piece this together but after researching this, I couldn’t figure out the correct laws of physics to combine to develop a formula to answer this question. Ex. 1 - A moving object impacts a static object at a constant velocity. Ex. 2 - A moving object impacts a static object at the same velocity but is accelerating at the moment of impact. Assuming the mass of the objects is the same and the velocity at the moment of impact...
