## Subtracting a scalar from each value in ...

Maple

Good Evening Everybody,

Would anybody show me how to subtract a scalar from each value in a list and output the results as list. Below is the problem am trying to solve, transforming the coordinate of the list to the origin (C.G). My goal is to output w =[ .....] and z = [.....]

#msub(mi("x"),mi("coord")) := [0., 2., 8., 10., 5., 5., 7.5, 7.5, 2.5, 2.5,

5.0, 5.0, 0]
#msub(mi("y"),mi("coord")) := [0., 10.0, 10.0, 0., 0., 2.0, 2.0, 3.0, 3.0,

## Numerical solution from procedure...

Maple

Good Afternoon,

Would anybody be kind to help me with the attached file. I have created procedures to calculate the Area, center of gravity , section modulus and moment of inertia of a cross section.

I'm testing the worksheet with an existing example from a text book, and the results are as follows

Area = 75*in2

Zxxtop = 119.219*in3

Zxxbott = 133.245*in3

Ixx = 629.212*in4

Zyyleft = 88.583*in3

Zyyright = 88.583*in3

Iyy = 442.917*in4

xbar = 4.722*in

ybar = 5.0*in

Good Morning,

Would anybody in the community please help me  to trouble shoot the problem with fsolve not producing result.

Regards,

## Using " If Statement"...

Maple

Good Morning Everyone,

Would anybody help me in the following if statement. What I would like is to compare the value of Az with the allowable, if it is less than allowable, I would like to print "O.K" , if not I would like toprint "N.G". In Maple I'm getting an error message, invalid terms in product. Please Help.

if (Az < 0.25*mm) then print "O.K" else print "N.G" end if;

<p>Good Morning Everybody,</p>
<p>I'm wondering what is wrong with the Maple code below, the worksheet works but Maple could not read L[1], L[2], L[3], and L[4] from the list param to give numerical solution. Would anyone be kind to tell me what is wrong with the code.</p>
<p>Regards,</p>

print(??); # input placeholder</p>
