Consider the frame shown in $($Figure $1).$ Suppose that $w=450l\frac{b}{f}t.$ Part B

Determine the moment of reaction at $A.$

Express your answer to three significant figures and include the appropriate units.

Enter positive value if the moment is counterclockwise and negative value if the

moment is clockwise.

Part C

Determine the $x$ and $y$ components of the reaction at support $B$ using scalar notation.

Express your answers using three significant figures separated by a comma.

$B_x,B_y=1$
