use this project to calculate yuris by changing the sliders the left formula is the simple one of y = m^2/s^2 the right formula is the complex one of y = ((n/m^2)(m^3))/kg
"The International Space Elevator Consortium has proposed a unit called the "Yuri", named after Yuri Artsutanov, to describe yield stress (or breaking stress) per unit of density of a material under tension. One Yuri equals 1 Pa⋅m3/kg or 1 N⋅m/kg, which is the breaking/yielding force per linear density of the cable under tension." - wikipedia
