Homework Statement
The attached jpeg shows a force plate with four measured masses each corresponding to a corner node. Calculate the center of mass on the force plate.
Homework Equations
I think they would be:
xcg = (x1M1 + x2M2 + x2M3 + x4M4) / (M1 + M2 + M3 + M4)
The ycg would be the same except you put yn in for xn.
The Attempt at a Solution
The textbook I've seen will place the lower left node at (0,0), thus zeroing out two of the nodes in each calculation. How does this give an accurate answer?
So for this method, the xcg would be:
xcg = (19*20 + 9*20) / (20 + 42 + 9 + 19)
Is this correct?
