I am using Mathcad Prime Release 8.0 and Datecode8.0.0.0

adding all the elements in the array p3(y) i.e all th eelements of the column

Here are the errors that I faced

Please attach your Prime worksheet (the .mcdx file), and explain the error that you observe (what is the result shown by Prime versus what did you expect it to be.

Success!

In the attached file under the Westergaards Exact formula , iam calculating pressure p3(y) . the array p3(y) is basically the pressure aalong the height . the total height is 600ft. iam trying to get the total force assuming width of wall is 1 ft perpendicular to screen.

the total force should be 1408kips based on these pressures

Hi,

Formula for pressure is integrated from 0 to h to get total force per unit width of wall.

Formula for location of centroid of pressure is also shown.
