a flexible piece of metal
It's a physical change, because bending a wire doesn't affect the chemical makeup of it.
it is not used to bending in that direction
to bend someting
When you bend a wire, the atoms inside the wire rearrange themselves to accommodate the bending. This can cause the wire to change shape and potentially weaken its structure. Over time, repeated bending can lead to the wire breaking or fracturing.
When a wire is bent back and forth, the continuous bending causes internal friction between the atoms of the wire, which generates heat due to the energy released from the bending motion. This phenomenon is known as mechanical hysteresis, where the repeated bending and unbending of the wire causes it to heat up.
Physical. The metal wire is still a metal wire after the change.
i guess both.
Bending a wire can change its resistance due to changes in its length and cross-sectional area. However, resistivity, which is an intrinsic property of the material, remains constant regardless of bending.
A Hot Wire Strip Heater
yes it can it the bow bending not the string stretching
the internal force is bending
To harden wire effectively, you can heat it to a high temperature and then cool it quickly, a process known as quenching. This will make the wire stronger and more resistant to bending or deformation.
