[QUOTE="BuckmasterStumpGrinding, post: 5998521, member: 121598"] A pendulum changes potential energy into kenetic energy. Pe=Ke MGH=(MV^2)/2 After finding your velocity at bottom plug it into the formula for centrifugal force. MAc=(MV^2)/R At this point you will have 2g's centrifugal force as the piece reaches the bottom. Add 1g for the weight of the piece and you have the total of 3 g's regardless of the weight or the length of rope. [/QUOTE]
