Hi All

Ive been racking my brains and i just can't remember how to calculate a 'seesaw' type balance point!?

Please see the attachment - It am trying to work out what 'C' is (I know A, B & D)

Thanks very much

You need to know the distances from below the centre of mass of each of the weights on the beam to the pivot point.

Call these E (on the left) and F (on the right).

Then A * E = B * F if the beam is balanced and weightless.

sorry i mean this

Hi

Sorry for the confusion - please see my new attachment with a more accurate diagram.

Basically i am trying to position a handle in the center of a product so when it is lifted it will be balanced.

Again im after 'C'

thanks very much

No, you have to know where the weights act on the beam.

This is below the center of mass of each weight and not at the end of the beam.
