Any short level Matlab project based majorly on mechanical engineering,vibrations can do.Here's some of basic work
%% Coulomb forced Vibration Graph Plotted
% function file
function xprime =c_f1(t,x)
W_n=3.5355;F_d=7.848;k=100;
xprime=[x(2);(-1)*(W_n)*(W_n)*x(1)-(((F_d)*(W_n)*(W_n))/k)*sign(x(2))+12.5*sin(5*t)];
%% Running File
xspan=linspace(0,16,1000);
x0=[1.3,0];
[t,x]=ode45(@c_f1,xspan,x0);
plot(t,x);
In images I have shown how inertia forces vary in SIngle Cylinder IC engine,my another work.
