What shape does an elastic band describe when hanging from two opposite points and suspending midway a weight W (causing deformation comparable to the droop without W)?

An elastic band, also known as a rubber band, is a flexible loop of rubber or latex that is used to hold objects together or to apply tension in various applications.
When an elastic band is stretched or put under tension, it experiences a restoring force that causes it to return to its original shape and length after the stress is removed. This behavior is known as elasticity.
The amount of stress an elastic band can handle depends on several factors, including its material composition, thickness, length, and the amount of stretching or load applied to it.
Stress in an elastic band is typically measured in units of force per unit area, such as pounds per square inch (PSI) or newtons per square meter (N/m²). It can also be measured in terms of the percentage of the band's original length that has been stretched.
If an elastic band is exposed to prolonged stress, it may eventually lose its elasticity and become permanently stretched out. This is known as plastic deformation and can occur when the band is stretched beyond its elastic limit.
