    Balance Point
AI Thread Summary
To calculate the balance point on a seesaw-type beam, the distances from the pivot to the center of mass of each weight must be known. The relationship A * E = B * F holds true for a balanced beam, where A and B are the weights and E and F are their respective distances from the pivot. The user is specifically trying to determine the position of 'C' for proper handle placement to ensure balance when lifted. Accurate measurements of the weights' positions relative to the pivot are crucial for this calculation. Understanding these principles will help achieve the desired balance in the product design.

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 I am 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.
 

Thread 'Why can't Solar panels be hemispherical, or a curved strip type?'

comparing a flat solar panel of area 2π r² and a hemisphere of the same area, the hemispherical solar panel would only occupy the area π r² of while the flat panel would occupy an entire 2π r² of land. wouldn't the hemispherical version have the same area of panel exposed to the sun, occupy less land space and can therefore increase the number of panels one land can have fitted? this would increase the power output proportionally as well. when I searched it up I wasn't satisfied with...
