Answer :
The technique entails disassembling the truss into separate portions and examining each section as a distinct rigid body.
The method of sections is typically the quickest and simplest way to identify the unidentified forces acting on a particular truss element. Ties, which are members that are being stretched, are tension members found in trusses.
The arrows are displayed pulling in on themselves as is standard practice in the business. The tension in a beam, on the other hand, pulls outward from the beam as depicted in the bottom diagram due to the tension forces.
