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.
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
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,
