Problem 14-79

Determine the horizontal displacement of joint B of the truss. Each A992 steel member has a cross-sectional area of 400 mm2 .

Step-by-Step Solution:

Problem 14-79Determine the horizontal displacement of joint B of the truss. Each A992 steel member has a 2cross-sectional area of 400 mm . Step-by-step solution Step 1 of 12 ^Consider moments about A. M A 0 RD(L AD) 5(AD) + 4(LAB) = 0Here, R is the reaction force at D and L is the length of the member AB. D ABSubstitute 2 m for LAD and 1.5 for LAB RD(2) 5(2) + 4(1.5) = 0 R = 2kN D
