Finding the center of mass?

Question

We have a wire of 1 m and we bend it in a shape of S. When I say "in shape of S" I mean by sides being verticals and horizontals not curvey sides.

Okay so Four sides of the shape of S are 22.22 cm and one side is 11.11 cm, making it 1 m. So how do I find the center of mass:

1) by hanging the configuration, S, from a string or hook.
2) by measuring the configuration, S, and calculating the Center of mass with formulas.

And one more thing the sides could be on any side it doesnt matter.

Thanks in advance

Answer 1

You seem to have the answers:

1. If you hang it from a string, the center of mass will be directly below the point of support. Use two different hanging points and ...

2. You can treat each straight piece as a separate bar whose length you know. If the bars are uniform, the center of mass of each is in the middle.

Give each of the 22.22 cm sides a weight of 1 and the 11.11 side a weight of 1/2.

Now you have 5 point masses with known position and known weights so the simple formulas will give you the center of mass.

So what's the question?
