When we bend a plastic ruler........ it bends in a specific plane in which the value of ots flexural rigidity is less i.e. in a plane where its moment of inertia is less............... it forms a deflection curve, the upper part goes into compression and the lower part into tension keeping a specific fibre called the neutral fibre the same in length. Also Bending stresses are developed which oppose the bending of the ruler.
This phenomenon is based on the theory of bending of beams under the scope of strength of materials

Which is more accurate a plastic ruler or a steel ruler?
Accuracy has more to do with the measurement lines on the ruler than the material. In terms of making measurements , however, a steel ruler has several advantages to a plastic ruler of the same accuracy. For starters, steel rulers are often thinner than plastic rulers, positioning the measurement lines closer to the paper. As well as this, many steel rulers feature a backing made of a gripping material such as cork, which keeps the ruler firmly planted while drawing lines and making measurements. Lastly, the measurement lines on steel rulers are frequently embedded into the metal, whereas plastic rulers tend to have the lines painted on. After a while, these marks can be worn away, reducing the accuracy and readability of a plastic ruler.
Why does a plastic ruler when heated melts while a steel ruler does not?
inshallah r u stupid or something. a steel ruler has a much higher melting point due to the giant lattice of electrostatic bonds, with very high heat energy need to the break them. on the other hand, the plastic ruler only contains weak intermolecular bonds, and thus little heat energy is needed.

Is the plastic wrap on a fruit roll up edible?
No it isn't. The plastic is used to keep the candy from touching itself. While the candy is edible the plastic can be harmful to your body.
Is glass more dense than plastic?
I believe so. If you had glass pieces and plastic pieces, and you threw them all in water, the plastic would float while the glas would sink. I hope this helped. ~;]]
Dissolve hard-water buildup on plastic?
To dissolve hard water buildup on plastic, the plastic can be sprayed with a solution of white vinegar and water. Let the solution stay on the material for a while, then wash with a dish soap and rinse well. Smaller pieces can be soaked in vinegar and water for a while, then washed.

Why does a hard wire break while bending it in the opposite direction?
it is not used to bending in that direction

What is the relationship between bending and strain?
From the Hooke law, stress s is proportional to strain e; s = Ee where E is elastic modulus of the material; the stress is the bending stress which varies from plus on one surface to minus on the opposite surface.
What is the difference between a straightedge and a ruler?
a straightedge need not have measuring increments (inches, centimeters, etc.) while a ruler is a straightedge with measuring increments
