Could someone help me with my solving problems?
Here is my code. I would like to have numerical answers
clear;clc;
E = 2*10^11;
I = 4*10^-4;
F = 10000;
l = 2;
syms x
Mx = @(x) (F.*x);
phix = @(x) int(Mx,0,l);
fx = @(x) int(phix,0,l);
%x = 0:x_step:l;
x_step = 0.01;
x = 0:x_step:l;
M = solve(Mx,x) ;

I have this and think it works how i would like it
clear;clc;
F = 10000;
l = 2;
x_step = 0.01;
x = 0:x_step:l;
syms t B
fx = int(F*t, 0, B)
result = subs(fx, B, x)
plot(result,x)

F = 10000;
l = 2;
x_step = 0.01;
x = 0:x_step:l;
syms t B
Mx = F*t; %generate the formula
fx = int(Mx, 0, B) %integrate it
result = subs(fx, B, x);
plot(x, result); %plot it
