## Homework Statement

Hello everyone,

I am currently working on a lab report investigating the spring back of a stainless steel ruler. I am trying to determine a relationship between the distance/angle that the ruler is bent (without warping it) and the amount of force exerted by the ruler.

Here are some pictures of the lab:

I've measured the x and y components of the ruler when bent (and the angle can be calculated) with various amounts of mass attached to the end.

## Homework Equations

Well, im trying to find the force exerted by the ruler against the bending force (gravity).

-The very basic equation is the force Fg=(mass of attached object) x gravity

-Since when the ruler is bent (with masses attached to the end), the Fnet of the mass is Zero.

## The Attempt at a Solution

Using Fg=mg

I was thinking, if an object is at rest on a table, the Fg=mg, and F normal= -mg. Bringing this idea to this ruler situation, if Fnet of mass=0, then F exerted by ruler is like F normal, and therefore is -mg.

But would the bending of the ruler play a factor in the force exerted by the ruler? Then using the angles and distances the ruler is bent, can an equation be found? I just want to know if i got the idea right.

And btw, any suggestions on a good graphing program?

-Thanks in advance,

regards,

steven
