hello everyone!
so as the title suggest, i wonder if anyone would have any idea to design a simple experiment to determine the bending strength and torsion of a plastic ruler.
it doesn't need to be extensive, as the value of the strenght itself isn't important. i just want to know e.g how far could the ruler bend before breaking. and when i have the result, i could compare it with another plastic ruler.
I don't have any measuring devide, all i have is a protractor and ill have some way of determining the angle of bend.
(i also have a dynamometer if that would help in any way)
here is my suggestion of the bending strength experiment:

for this experiment i just put the ruler on the table and apply F at the end and determine the angle. Although it is actually pretty inaccurate to read the angle to determine its strengh :/
and here another suggestion:

i put the ruler on 2 objets and apply F to the middle part.ill determine how far will it bend in cm.
Do you guys have any suggestion for this experiment? as i said, i have limited device and i would prefer an experiment as simple as possible.
Also, i would be needing a design experiment to determine the torsion of the plastic ruler too. Alhthough i don't really know how to do it without proper measuring divide :/
So i would appreciate if anyone could give an idea about it! Thank you!
