Shear force and bending moment diagrams show the variation of forces and moments along a beam subjected to different loads.

• Shear force diagram represents the variation of shear force along the length of the beam.

• Bending moment diagram represents the variation of bending moment along the length of the beam.

• Different loads such as point loads, distributed loads, and moments can be combined to create a composite load on the beam.

• To draw the shear force diagram, calculate the rea...read more

Different grades of steel have varying yield stress. Learn about them here.

• The most common grades of steel are A36, A572, and A992.

• A36 steel has a yield strength of 36,000 psi.

• A572 steel has a yield strength of 42,000-65,000 psi depending on the grade.

• A992 steel has a yield strength of 50,000-65,000 psi depending on the grade.

• Higher grades of steel generally have higher yield strengths.

Vibrators are used to generate vibrations for various purposes.

• Vibrators are commonly used in construction to compact concrete and remove air bubbles.

• They are also used in industrial applications to facilitate material flow in hoppers and chutes.

• In the field of electronics, vibrators are used in devices like cell phones to provide haptic feedback.

• Vibrators are used in sexual wellness products for stimulation and pleasure.

• They can also be used in medical settings for therapeut...read more

Fy in steel indicates the yield strength of the material.

• Fy is a parameter used to measure the stress at which a material begins to deform plastically.

• It represents the maximum stress a material can withstand before permanent deformation occurs.

• Fy is typically expressed in units of force per unit area, such as pounds per square inch (psi) or megapascals (MPa).

• Knowing the Fy of a steel is important for structural design and determining the load-bearing capacity of a component....read more

The density of steel is higher than that of concrete.

• Steel has a density of around 7.8 g/cm³, while concrete typically has a density of 2.3 g/cm³.

• The higher density of steel makes it stronger and more durable, but also heavier.

• Concrete, on the other hand, is less dense but still provides good structural strength.

• The density of steel and concrete can vary depending on the specific composition and additives used.

A megger is used to measure the insulation resistance of electrical wires and equipment.

• Used to detect insulation faults in wires and cables

• Helps prevent electrical breakdowns and accidents

• Can identify deteriorating insulation before it causes damage

• Commonly used in electrical maintenance and testing

• Example: A megger can be used to test the insulation resistance of a motor winding

The Bernoulli theorem states that in a flowing fluid, an increase in the speed of the fluid occurs simultaneously with a decrease in pressure or a decrease in the fluid's potential energy.

• States that in a flowing fluid, an increase in speed occurs simultaneously with a decrease in pressure or potential energy

• Describes the relationship between fluid speed, pressure, and potential energy

• Used in fluid dynamics to analyze the behavior of fluids in motion
