Question: 1 0 - 1 6 . The member EF in the truss shown in Figure P 1 0 - 1 6 carries an axial tensile

10 - 16 .

The member EF in the truss shown in Figure P

10 - 16

carries an axial tensile load of

54000

lb in addition to the two

1200

lb loads shown. It is planned to use two steel angles for the member, arranged back to back. Specify a suitable size for the angles if they are to be made of ASTM A

36

structural steel with an allowable stress of

0.6

times the yield strength.
