The A

-

frame shown supports a

100

N force DD at the midpoint of member

A B,

as shown.

Determine the scalar components of the reactions at pins A and

C .

Note: the sign of a scalar component indicates the sense of the force. A positive sense indicates that the force points towards the positive end of the corresponding axis.
