A truss is made up of elements 1 2 and 3 as shown in Figure

A truss is made up of elements (1), (2) and (3), as shown in Figure 3.3 below, with each element having the same elastic modulus E. yield strength sigma_Y and cross-sectional area A. A vertical force P acts downwardly on joint C. What is the largest load P that can be applied for a factor of safety of FS = 2 for the structure? What are the horizontal and vertical components of displacement of joint C in the truss? Leave your answers in symbolic form in terms of variables defined here in the problem statement.

Solution

The answer of the following questions are as follows

a) The largest load P that can be applied for a factor of safety =2 for the structure is 186 N.
