How to get integral function

Download the file ‘Loading.txt’ from Blackboard. The file contains the load distribution on a joint. The first column contains the position data (in meters) and the second column contains the load distribution in N/m.

a. In MATLAB, load the contents of the file and plot the distributed load as a function of position.

b. Using the function ‘trapz’, find the magnitude of the resultant force.

c. Find the location of the resultant force.

Answer 1

[Walter Roberson]

trapz(Position, Load)

perhaps.

[Sarah Hicks]

That worked for the trapz function. Any idea on how to do part C?

[Walter Roberson]

Only if the force vector is consistently negative on one side and consistently positive on the other, then finding the zero crossing might make sense as a location. But otherwise I do not think I understand what "location" means in the sense of a 1D vector.
