## MATLAB Animation Tutorial – Crank Slider Mechanism

In this video I write a simple code in Matlab to animate a crank slider mechanism, but before I show some geometry.

a=2; b=5;
P1=[0 0];
axis(gca, ‘equal’);
axis([-2 7 -2 3]);
k=1;

for t=1:500
theta=k*(t/10);
P2=a*[cos(theta) sin(theta)];
alfa=asin(a*sin(theta)/b);
P3=[(a*cos(theta)+b*cos(alfa)) 0];
crank=line([P1(1) P2(1)],[P1(2) P2(2)]);
slider=line([P2(1) P3(1)],[P2(2) P3(2)]);
P2_traj=viscircles([0 0],a,’LineStyle’,’–‘);
P1_circ=viscircles(P1,0.1);
P2_circ=viscircles(P2,0.1);
P3_circ=viscircles(P3,0.1);
pause(0.001);
delete(crank);
delete(P1_circ);
delete(slider);
delete(P2_circ);
delete(P3_circ);
end

Cool! Thanks for the sharing this work!

Hi , can you tell me how can i change the angula veloccity k? why is that when I change the k value , the figure cease to move.

thank you for sharing this work it good and help me 🙂

chi yung says:

Can you provide your code please?Cause i followed your steps, i wasn’t success however. It said that my crank was undefined.

theghostmachine says:

Thanks, This helped so much. Can you do a tutorial of a more complicated crank slider mechanism, one with sliding pairs.

basedonprinciple says:

Can someone explain why for the crank = line([P1(1) P2(1)], [P1(2) P2(2)]) what the (1) and (2)’s do?

Could you please provide this code? I’m having a hard time following

Can you help me make a mechanism?
