SFD stands for Shear Force Diagram and BMD stands for Bending Moment Diagram in structural analysis.

• SFD shows the variation of shear force along the length of a beam or structure.

• BMD shows the variation of bending moment along the length of a beam or structure.

• Both diagrams are essential for analyzing the internal forces in a structure.

• They are commonly used in civil and mechanical engineering for designing and analyzi...read more

Thrust forces for beams can be calculated using equations of equilibrium and considering external loads.

• Calculate the sum of all external forces acting on the beam.

• Determine the direction of the forces (compression or tension) based on the beam's support conditions.

• Apply equations of equilibrium to calculate the thrust forces at different points along the beam.

• Consider any distributed loads or moments that may affect t...read more

A transformer can be charged by applying a voltage to its primary winding.

• To charge a transformer, connect a power source to its primary winding

• The voltage applied to the primary winding creates a magnetic field

• This magnetic field induces a voltage in the secondary winding

• The transformer is charged and ready to transfer power

Parts of a transformer include the core, windings, and insulation.

• Core: Provides a path for magnetic flux and is usually made of laminated iron or steel.

• Windings: Consist of primary and secondary coils, which are wound around the core.

• Insulation: Prevents electrical leakage and is used to separate the windings and core.

• Tap changer: Allows for voltage regulation by changing the number of turns in the winding.

• Cooling sys...read more

Motor starters are used to control the starting and stopping of motors in various applications.

• Motor starters help protect motors from overloads and short circuits.

• They provide a convenient way to start and stop motors remotely.

• Motor starters can also provide under-voltage and over-voltage protection to the motors.

• Examples of applications include industrial machinery, HVAC systems, and water pumps.

The power triangle represents the relationship between real power, reactive power, and apparent power in an AC circuit.

• The power triangle is a visual representation of the relationship between real power (P), reactive power (Q), and apparent power (S) in an AC circuit.

• Real power (P) is the actual power consumed by the circuit and is measured in watts (W).

• Reactive power (Q) is the power that flows back and forth between...read more
