### 9.1 Example 1

Calculate the resultant, at point A, of the forces applied to the piece.

Solution with FisicaLab

Select the group Static and, inside this, the module Static of solids. Erase the content of the chalkboard and select the SI system. And add one element Points, four elements Point, one element Resultant and three elements Force, as show the image below:

To the element Points, we call this Piece:

Name

Piece

To the element Point that represent the corner A, assuming this is at the origin, we have:

Name

Piece

x

0

y

0

Now to the element Point at corner B:

Name

Piece

x

30 @ cm

y

20 @ cm

And to the applied force at this corner:

f

20

To the element Point at corner C:

Name

Piece

x

75 @ cm

y

20 @ cm

And to the applied force here:

f

30

ang

55

To corner D:

Name

Piece

x

45 @ mm

y

0

And to the force:

f

17

ang

40

Now to the element Resultant:

M

Mr

f

Fr

ang

angr

Now click in the icon Solve to get the answer:

```Mr = -2.296 N*m ;  Fr = 33.906 N ;  angr = 277.089 degrees ;
Status = success.

```
