#### Basically: **Method** **of** joints is an **analysis** technique to find the forces in the members of a **truss**.It looks at each joint individually using the particle equilibrium equations. Application: To calculate the loads on bridges and roofs, especially if you need to know all of the values of the members.. Looking Ahead: The next **section** explores a **method** to solve one or two members of a **truss**. **Truss** Node Connections 14 Direct connections • Members are welded directly to one another, without the need for gussets or other elements (e.g. tubular joints). • When the chords are made from large angles or tee-**sections**, it is possible to connect angle web members directly to the chords. 1. first of all, create a cut to divide the **truss** into segment, passing the cut through members where the force is desirable. 2. Create the cut through three member of a **truss** due to the fact that with three equilibrium equations viz. we can resolve for a maximum of three forces. 3.

**section**

**method**is an effective

**method**when the forces in all members of a

**truss**are to be determined. If only a few member forces of a

**truss**are needed, the quickest way to find these forces is by the

**method**

**of sections**. In this

**method**, an imaginary cutting line called a

**section**is drawn through a stable and determinate

**truss**..

**Method**

**of**

**Sections**: If only a few of the member forces are of interest, and those members happen to be somewhere in the middle of the

**truss**, it would be very inefficient to use the

**method**

**of**joints to solve for them. In such cases an alternate procedure based on the so-called

**method**

**of**

**sections**is used..

**Method**

**of**

**sections**has its roots in the principle stated earlier, viz., if a body is in. 4

**Method**

**Sections**" The second

**method**

**of**

**truss**

**analysis**that we will consider is called the

**method**

**of**

**sections**. " The

**method**

**of**

**sections**depends on our ability to separate the

**truss**into two separate parts, hence two separate FBDs, and then perform an

**analysis**on one of the two parts.
