how u solved it my friend?

i know that Q=V x A..SO--> 4V x A=V x (A-a) and then i can find A..Is that right?

hello..i m phasing a problem..i have an hydraulic circuit with pressure 72 bar and i want to find the cylinder diameter. I have that rod diameter is 15 mm and the speed of the cylinder is 4 times higher than the rod..please help me because i seraching days for this solution which i m sure that...

so at the yield loci graph the von mises will be smaller than the tresca right? i mean that the circle(von mises) will be inside of the hexagon(tresca) if i m right..

the same with me..;p

thnx for reply..i don't think so that i have error with my solutions because i solved them a 1000 times..:) i have a compressive stress 16.55 MPa and shear stress 95.5 MPa. So the principal stresses are.. σ1=87.5 and σ2=-104.1. Right?;p i think may be my wrong is on principal stresses..(signs)...

hello there i have a shaft..i found the von mises and the tresca..von mises is 360 and tresca is 430. So when i m trying to produce the loci graph the tresca will be bigger than von mises. I search in internet and there is no examples like that. Is there a problem if the tresca is bigger than...
