Question

i) A 35 kg body is supported by the flexible cable system as shown in Figure 1 i. Determine the tensions in cables A, B, C and D. 125° 35° B с D A 140° M Figure 1 i. ii) Enlist different assumptions made in the analysis of truss.

Answer 1

Answer (1) assumption made in truss ③ Self wt of truss members is neglected. , loud is applied only at points which may be Horizontal, inclind, vertical, Axial force will be cleveloped in fruss members and truss members is free from Shear Force and Berling moment, and Oxial Force should be with in elastic limit Ansar ci Tosin 50' TO 150 TD Cos50 TA mg 35x9.31 = 343-35'N Efy=0 Tosin 50' = 343.35 TD. 448.21N EFX=0 To os 50 = TA TA - 888.ION
