Actually, i have values for p, η0, ηr, θ0, θr,
for example:
p=101325,
η0=4.43,
ηr=0.181,
θ0=313.15,
θr=373.15,
also, as you can see, it is possible to solve α , because these 5 equations can be combined into 1
Equation 1:
Equation 2:
Equation 3:
Equation 4:
Equation 5:
I would like to solve , (not the one with a star)
and i want to define values for p, η0, ηr, θ0, θr.
i have tried to solve them, but didn't work,
can someone please help and show me step by step?
suppose i have 4 solids like this:
and the solid have shear stress and tensile stress 12N/mm2 and 15N/mm2 respectively,
suppose i know the area of each surface,
how can i judge whether this solid is able to withstand 20N load?
what kind of formula should i use?
