The Warren truss is used to support a staircase. Determine the force in members CE, ED, and DF, and state whether the members are in tension or compression. Assume all joints are pinned.

A. ED = 3.60 kN T, DF = 1.70 kN C, CE = 6.22 kN C
B. ED = 2.00 kN C, DF = 2.26 kN C, CE = 2.26 kN T
C. ED = 0.800 kN C, DF = 1.131 kN T, CE = 2.83 kN C
D. ED = 0.400 kN C, DF = 2.26 kN T, CE = 4.53 kN C
