Required information

A truss used for supporting signs over an expressway is shown. The truss is supported by a pin at joint A and a horizontal link at joint $B.$ Given that $W=460lb.$

NOTE: This is a mult$-$part question. Once an answer is submitted, you will be unable to return to this part:

Determine the force supported by the five members that emanate from joint $l$ Enter forces as positive numbers if the member is in tension and as negative numbers if the member is in compression.

The force supported by the five members Alat emanate from joint I is as follows:

$T_{1J}=$ Ib

$T_{IL}=lb($Round the final answer to four decimal places.$)$

$T_{IK}=Ib14$
