Plotting curves with increasing radius.

for dout = 11:0.5:100 for din = 1:0.5:90 mn = 5; mf = pi/4*(dout*dout-din*din)*13*7890*10^-6; k = dout/2^0.5; rn = 5.5;

    J = (mn*rn^2 + mf*k^2)*2*pi/rn;
    plot(dout,J);
    end
end

Hi, I am using this code to plot dout vs J. But i end up getting only one value. how should i modify this code?

Thanks, karthik.

Are you expecting this?

dout = 11:0.5:100 ;
din = 1:0.5:90 ;

mn = 5;
mf = pi/4*(dout.*dout-din.*din)*13*7890*10^-6;
k = dout/2^0.5;
rn = 5.5;
J = (mn*rn^2 + mf.*k.^2)*2*pi./rn;
plot(dout,J);

It is not working.

I want to plot dout vs J.

It throws some error at mf

Error using * Inner matrix dimensions must agree.

Error in Plotting (line 5) mf = pi/4*(dout*dout-din*din)*13*7890*10^-6;

The above code, what I have copied will work. How you have tried the code?
