Hey,
So I am currently trying to workout the fatigue characteristics of my Formula Student Space frame design, I am using Cold Drawn Seamless mild steel.
I have the following mechanical properties:
Re - 360 MPa
Rm - 450 MPa
I think these are the effective stress intensity range and...
Hey,
Does anyone know the unique features of mixed refrigerants and why they mix refrigerants instead of using just pure refrigerants?
Thanks,

Hey,
I am trying to determine the importantance and difference of fouling in sizing the evaporator and condenser in a Refrigeration cycle?
Thanks,

Homework Statement
A thin beam of length L (flexural Stufness EI, cross-sectional area A, density p) is connected to a linear spring of stiffness K_s at each end. Derive the governing equation for the natural frequencies of transverse vibrations from the beam equation and boundary conditions...
Homework Statement
A cord of length L density p and cross-sectional area S is under tension T with the left end fixed and the right end attached to a spring-mass sstem. Show that the equation for the natural frequencies is given by:
tan(wL/c) = -(T/kL)((wL/c)/(1-(w/w_n)^2))

Brilliant I will work on that, in the mean time I am also woking on another paper I have got very far however I cannot seem to calculate the reduced ideal density, I understand the formula however I do not understant where the range of densities come from? Here is the link to the paper...
I am currently trying to explain in an assigment different papers on refrigerants, one of the ways in which this is being done is by reproducing the results which were obtained in the paper, I am currently trying to explain the results which were found by calculating one set of results for each...
By using the PR equations I am assuming the following 2 equations:
Tr=T/Tc
Pr=P/Pc
Am I assuming that T= the evaportaing temperature or the condensing temperature?
