In the given figure, the horizontal platform ABCD weighs $60-1b$ and supports a $370-lb$ load at its center. The platform is normally held in position by the hinges at A and $B$ and by braces $CE$ and $DE.$ Consider brace $DE$ is removed. The hinge at A does not exert any axial thrust.

$$

Determine the reactions at hinges and the force exerted by the remaining brace CE$.($Include a minus sign if necessary.$)$

The force exerted by the brace CE is $$ lb$.$

The reaction at $A$ is $(|$lb$)1.$

The reaction at $B$ is $($ lb$)$ lb$)$ J $+($

lb$)k.$
