Hello,
Some classmates and I are building a remote controlled robotic lawnmower for a design project. One of my task is to design the blade system. The blade is a small weed-wacker blade that is 12in long -- and I am estimating the weight at 1lb for now. It will be attached directly to the motor output shaft.
I am having trouble figuring out how much torque I will need to turn the blade with an electric motor. Neither my dynamics or mechanical mechanisms book gives a clear example of a bar/blade that is driven from the center and/or facing down. Can someone help me figure out the math to come up with some calculations for this problem?
-Thank you
