We want to construct the truss structure shown in Fig. 2. The structure has been designed to carry a vertical downward force of 5 kip applied at joint 3.---**Figure 2 Description:**- A triangular truss structure with: - Joint 1 connected to Joint 2 at the top, placed horizontally 10 ft apart, with supports at both ends. - A midpoint titled Joint 3 forms a triangle, located directly beneath Joint 1 and Joint 2. - Vertical dimensions and details: - Distance between Joint 1 and Joint 3: 10 ft - Additional horizontal divisions: 4 ft from Joint 1 to a midpoint, and 6 ft from this midpoint to Joint 2. - A vertical force of 5 kip is applied downwards at Joint 3.- Material properties for all members: - Elastic modulus (E): 29000 ksi - Cross-sectional area (A): 10 in²---**Tasks:**a) Calculate the vertical displacement of joint 3.b) The construction of the truss has already begun, and the members 1-3 and 2-3 have been fabricated and shipped to the construction site. You receive a call at 11 pm from the owner who wants the vertical displacement of joint 3 to be zero. Considering that member 1-2 is to be fabricated the next day, propose a solution to satisfy the owner without redesigning and fabricating a new truss structure.

You are relaxing at home, when suddenly you get a call (at 11pm) from the owner of the structure and are informed that they want the vertical displacement of joint 3 to be zero. Given the fact that the remaining member, 1-2, is going to be fabricated the next morning, can you imagine a way to satisfy the owner without having to design and fabricate a different truss structure from scratch?
