  5. Calculating Viscosity is the viscosity of the substratum in poises f represents the dimensions of the load ρ = 3.4 gcm/3, the density of the substratum g is the acceleration caused by gravity on earth, 9.8 m/s2 k = 1/Tr , time 0f rebound is 4000 yrs Solving for viscosity gave a value of 0.96 x 1021 poises, or 1021 poises
