Concept explainers

Types of loading

In mechanical terminology, the term load indicates that external force/weight, either constant or variable, acts on a mechanical member/structure. The weight of an object of a specific material is also an external load, and the external force that works on a structure comes under the categories of loading. The external load generates its effects as stress and strain in the structure.

Question

### Structural Analysis: Truss Load Evaluation

#### Problem Statement

**6.42** A floor truss is loaded as shown. Determine the force in members \( CF \), \( EF \), and \( EG \).

#### Diagram and Description

The diagram depicts a truss structure subjected to several vertical loads at multiple points. The truss layout is as follows:

- **Supports:**
- Support at point \( A \) is depicted as a pin support.
- Support at point \( K \) is depicted as a roller support.

- **Load Distribution:**
- Point \( B \) has a downward load of 250 lb.
- Point \( D \) has a downward load of 500 lb.
- Point \( E \) has a downward load of 500 lb.
- Point \( G \) has a downward load of 375 lb.
- Point \( H \) has a downward load of 250 lb.
- Point \( L \) has a downward load of 125 lb.

- **Spacing:**
- Between each load application point (B, D, E, G, H, J) and their adjacent nodes, the horizontal distance is consistently 4 feet.
- The distance from point \( I \) to point \( K \) is 2 feet.

The truss's nodes and the arrangement are denoted by alphabetic labels from \( A \) to \( L \). This framework must be analyzed to find the force within specific members noted as \( CF \), \( EF \), and \( EG \).

#### Figure Reference
