A wiring diagram usually gives information about the relative position and arrangement of devices and terminals on the devices, to help in building or servicing the device. This is unlike a schematic diagram, where the arrangement of the components' interconnections on the diagram usually does not correspond to the components' physical locations in the finished device. A pictorial diagram would show more detail of the physical appearance, whereas a wiring diagram uses a more symbolic notation to emphasize interconnections over physical appearance.

A wiring diagram is often used to troubleshoot problems and to make sure that all the connections have been made and that everything is present.

Architectural wiring diagrams show the approximate locations and interconnections of receptacles, lighting, and permanent electrical services in a building. Interconnecting wire routes may be shown approximately, where particular receptacles or fixtures must be on a common circuit.

Wiring diagrams use standard symbols for wiring devices, usually different from those used on schematic diagrams. The electrical symbols not only show where something is to be installed, but also what type of device is being installed. For example, a surface ceiling light is shown by one symbol, a recessed ceiling light has a different symbol, and a surface fluorescent light has another symbol. Each type of switch has a different symbol and so do the various outlets. There are symbols that show the location of smoke detectors, the doorbell chime, and thermostat. On large projects symbols may be numbered to show, for example, the panel board and circuit to which the device connects, and also to identify which of several types of fixture are to be installed at that location.

A set of wiring diagrams may be required by the electrical inspection authority to approve connection of the residence to the public electrical supply system.

Wiring diagrams will also include panel schedules for circuit breaker panelboards, and riser diagrams for special services such as fire alarm or closed circuit television or other special services.

Definition of Shear Force and Bending Moment Shear force is taken ve if it produces a clockwise moment and it is taken ve when it produces an anticlockwise moment. Bending moment at any point along a loaded beam may be defined as the sum of the moments due to all vertical forces acting on either side of the point on the beam.

At any point within a beam, the Bending Moment is the sum of: each external force multiplied by the distance that is perpendicular to the direction of the force. Shearing Force The shearing force (SF) at any section of a beam represents the tendency for the portion of the beam on one side of the section to slide or shear laterally relative to the other portion.

APPLICATION OF SHEAR FORCE AND BENDING MOMENT: One of the most significant applications of shear force and bending moment diagram is that we can calculate how much area of steel is required for the section of the structural member while designing any of the structural members such as beam, column or any other member.

Shear force is taken ve if it produces a clockwise moment and it is taken ve when it produces an anticlockwise moment. Bending Moment – Bending moment at any point along a loaded beam may be defined as the sum of the moments due to all vertical forces acting on either side of the point on the beam. The bending moment tries to bend the beam.

After the support reactions are calculated, the shear force and bending moment diagrams can be drawn. Shear force is the force in the beam acting perpendicular to its longitudinal (x) axis. For design purposes, the beam's ability to resist shear force is more important than its ability to resist an axial force.

Shear force is basically defined as the algebraic sum of all the vertical forces at any section of the beam either left hand side or right hand side of the section. Shear force is also a type of force and hence its unit will be Newton.

Types of beams Effects of loading on beams The force that cause shearing is known as shear force The force that results in bending is known as bending moment Draw the shear force and bending moment diagrams SHEAR FORCE & BENDING MOMENT •Members with support loadings applied perpendicular to their longitudinal axis are called
