Poisson ratio of most linear elastic material can be anywhere between 0 and 0.5.
It is pretty close to 0.5;

I am looking for the formula to figure strength to weight ratio for a dome that I built for a project
Deviation ratio: In a frequency modulation system, the ratio of the maximum frequency deviation of the carrier to the maximum modulating frequency of the system under specified conditions

Poisson's ratio is 0.3 for metals because the metals begin to get thinner the more they are stretched. It also relates a strain that is tensile to a strain that is compressive.Ê

since k=E/3(1-2n): where k=bulk modulus and n=poision's ratio it can be seen that value of poision's ratio can't be smaller than 0.5 in order to keep k be +ve.hence poision's ratio is 0.5
It depends. Some simply use an angle they find pleasing to the eye. For maximum strength many guide use a 6:1 ratio for softwood and a 7:1 ratio for hardwood.
Road building codes are in place to meet load requirements. The design strength of roadways must be higher than expected maximum loads. These load factors are, roughly, a ratio of the theoretical design strength to the maximum load expected in service.
