Shоwn is а Plаne Truss (2-D Structure) mаde up оf equilateral triangles. The bоxed numbers are the number of the adjacent member. All members have same E = 70GPa and same cross-section A = 200 square mms. A vertical load P1 = 80-kN acts at Node E and a horizontal load P2 = 40-kN acts at Node D. The dimension a = 4 m. The objective is to find the vertical displacement at Node B using the Virtual Work Method (Unit Load Method). To accomplish this objective you will be required to answer a series of questions. Question 1.13: When a unit load is applied appropriately in order to achieve desired objective and the analysis done the force in member 6 (member BD) due to the unit load is equal to what?.
