my objective was that gravity caused movement in an object without lowering the center of mass
i built a balance that has the center of gravity in the axe:
i used a 60 cm long 1 cm thick wood beam, i put a nail in the middle as an axe,
i put 100 grams of plastiline in each end of the beam
first try the CoM was lower than the axe what would be noticed because turning upside down the beam it wouldn level
the way to make sure the CoM is in the axe is by trying the balance normal and upside down
ive noticed it even has a period which by the way i was given here and deppends on the mass and length of the beam not how low the CoM is from the axe as is the case of a pendulum
my next step is freezing the plastiline to make sure the CoM is not lowered by the weight
anny suggestion of what I am doing wrong or how this is posible?
