hello could someone help me with this problem

I have to fixed ends with 700 lbs on one end with 14 psi pushing on it. My length is 25 inches, I used the vmax equation

vmax = (P * L^4)/(384 * E * I)

P = 14 psi
L = 25^4
E = 29 * 10^6
I = (could someone help me solve for I or do you know the equation)

Thank you

actually the formla for max deflection
i.e deflection at center generally is equal to,
delta= 5*p*(l^4)/384*e*i
where p- force per unit length
i- polar moment of inertia = (B*H^3)/12 for a rectangular crossection with b- width, h -height of rod

Boobed in the response
it should read I = PL^4 / 384EV

transposing is easy I = PL^4 / 384ei
HOWEVER i WOULD BE SURPRISED IF P WAS A PRESSURE, I WOULD HAVE THOUGHT IT WAS A LOAD.
