Forces
显示 更早的评论
f(z)=((10*z)/(5+z))*exp(-2z/10);% wind force
% total force
F=intergral(0 to L) of f(z)dz;
length(z)=10
This force is completely balanced by the Tension, T, in the left support cable (while the right support cable is limp). The mast is fixed to the deck so that it transmits horizontal and vertical forces, but does not transmit moments.
1.Graph (using a well labelled MATLAB graph) the wind force, f(z) against z.
2.Using MATLAB integration techniques determine the total equivalent force acting on the mast

This seems to be a homework question. Of course, you have to solve your homework by your own. So what kind of help do you expect? Do you have a specific question?

What is meant by "length(z)=10" ? Is that supposed to mean that when you do a numerical integration, you are only to use a total of 10 points? Or is it intended to mean that the L mentioned in the line defining F should be 10? Or is it hinting that this is an integral along a curve? Note that it will only be possible to find the total force if L is known.
