Webb8 maj 2016 · π r 2 P = 2 π r σ t P = 2 σ t r Because balloons get thinner as they stretch, the thickness will actually vary. Rubber typically has a poisson's ratio of 0.5 meaning it keeps a constant volume while being deformed. We can then calculate the thickness in terms of the radius: t r 2 = t 0 r 0 2 t = t 0 ( r 0 r) 2 Putting them all together: Webb21 jan. 2024 · The idea is to calculate the temperature after the reaction from the stoichiometry of the reaction (assuming no excess air), the heat of the reaction, and the …

WebbWith the introduction of Balloons, we added a different formula for how fall damage is calculated. The new formula uses velocity (as opposed to fall height), and we probably made it a bit too aggressive. We’re currently working on a hotfix to reduce the damage amount in similar scenarios so it’s non-lethal. terrace tea rooms and bed breakfast
