Question $2$

The A$-$frame shown supports a $125$ lbs force D at the midpoint of member AB and a $300$

lbs$*$ft clockwise moment M$\_($E$)$ at E 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 the

force points towards the positive end of the corresponding axis.

A$\_($x$)=,$A$\_($y$)=$

C$\_($x$)=$

xC$\_($y$)=$
