Question

A key point is that in Matlab the equals sign, "=", is an assignment. It takes the result of what is on the right side and puts it in the place named on the left side. Matlab is a script language so it works one line at a time from top to bottom.

For this discussion describe what each code snippet does and how it might be used in Statics. Describe in general terms what Statics calculation is being performed by each code snippet. What is input to the calculation and what results are given? Give definitions not numbers. All of these involve some concept covered in this module.

Code 1

Magnitude = 5;
Angle = 210;
X = Magnitude * cosd( Angle )
Y = Magnitude * sind( Angle )

Code 2

Xcomponents = [ 1, 2, -3, 4 ];
Ycomponents = [ 3, -6, 5, 0 ];
ResultantX = sum( Xcomponents )
ResultantY = sum( Ycomponents )

Code 3

Rx = -6;
Ry = 8;
Magnitude = sqrt( Rx^2 + Ry^2 )
Angle = atan2d( Ry, Rx )

Code 4

Magnitudes = [ 5, 13, 17 ];
Angles = [ 53.13, 157.38, -28.07 ];
X = Magnitudes .* cosd( Angles )
Y = Magnitudes .* sind( Angles )

Code 5

F = [ 1, 2, 3, 4 ];
AngY = [ 0, 30, 120, 80 ];
phi = [ 30, 60, 90, 270 ];
Fh = Mag .* cosd( angY );
X = Fh .* cosd( phi )
Y = F .* cosd( AngY )
Z = Fh .* sind( phi )
