Concept explainers

Cables

Cables are collections of wires, alternatively referred to as a cord, connector, or plug. They are one or more wires covered in a plastic covering that allows for the transmission of power or data between devices. The earliest use of recognizable electrical cable was the early commercialized telegraph lines. These were iron-made and tedious to produce and install cabling.

### Problem Description

A mechanism supports a structural assembly involving a bar ABC and a cable DE. A turnbuckle T on cable DE is used to adjust the position of roller D to keep bar ABC level.

- **Bar ABC**:
- Supports a uniformly distributed load of 636 lb/ft across its entire length.
- Carries a concentrated load of 1,272 lb at its end point C.

- **Cable DE**:
- Attached to roller D which can move to maintain the level of bar ABC.
- Forms an angle of 60° with the horizontal.

### Dimensions

- The span between D and E is 10 ft, divided equally into two segments of 5 ft each.

### Tasks

Determine the following forces:
- Force at pin A, \( F_A \)
- Force at pin B, \( F_B \)
- Tension in cable DE, \( F_{DE} \)

Inputs required are the magnitudes of these forces in pounds (lb).

### Diagram Explanation

- A line diagram of the structure is shown with:
- A horizontal beam ABC supported at A and B.
- A vertical reaction at point B connecting to a slanted cable DE at a 60° angle from the horizontal.
- The beam carries a distributed load, indicated by arrows along its length, and a point load at the end C.

This problem involves analyzing a statically determinant structure to find the reaction forces and tension caused by these loads.
