This occurs somewhere in between the equilibrium point and the extreme point (extreme point is when x ... WebAn elastic band which is 72 cm long, is stretched to 90 cm.

The work w is F∆D-P∆V, (the P∆V term is very small), and ∆H= q + F∆D-P∆V- (F∆D-P∆V) = q. Since we heated the band up, ∆H= q>0. This can be done reversibly, so that: Δ S h e a t = Δ d q r e v T > 0 WebWhen forces pull on an object and cause its elongation, like the stretching of an elastic band, we call such stress a tensile stress. When forces cause a compression of an object, we call it a compressive stress. acnh pelican on beach WebFeb 13, 2024 · Strain is defined as the measure of deformation – a proportion between the change of length and the original length of an object. For example, if you take an elastic band and stretch it so that it is twice longer than initially, then the strain will be equal to 1 (100%). The formula for strain is:
