Question

Please all the questions. Give an estimate guess if u can't compute answer

Identify the zero-force members in the truss shown. 10 000 N 10 000 N 10 000 N (A) GI, HI O (B) AB, GH O (C) AB, HI, GI O (D) AB, GH, GI, HI, EG

Answer 1

Prob.1 (D)

IH, IG, GE, GH, and AB.

Prob.2 (D)

It is convenient when three or less than three member forces of a section are to be determined in a determinate truss.

Prob.3 (B) is the most near balue.

F= sum of forces or friction on the top and bottom surface of the central block = (0.2*50 + 0.2×100)*9.81 = 294.3 N
