Pratt truss. State if the members are in tension or compression.

Pratt truss. Consider the following inverted Pratt truss. 17 Determine the force in each member of the Pratt roof truss shown. 8 - Enhanced - with Hints and Feedback <38 of 30 Review Determine the force in members LK KC and CD of the Pratt truss (Figure 1). Suppose that P1=18kN,P2=27kN, and P3=36kN. 6-11 Question: 6. 400 N 300 N D С E B F 3 m А G LK JIH Н 12 m, 6 @ 2 m Prob. Part B Determine the force in member KC of the Pratt truss Question: Suppose that P1=12kN,P2=18kN, and P3=24kN. Suppose that P =30kN,P 2 =45kN, and P 3 = 60kN (Eiguie 1) Figure Detormine the force in member LK of the Pratt truss Express your answer to three significant figures and include the appropriate units. Determine the zero-force members in the Pratt roof truss. Enter negative value in the case of compression and positive value in the case of tension. j6 12u 0g5um ki28jwny zdn oi7ydu vliif ayr mdb4xc 1r
