A shear force bending diagram of an overhanging beam shows the variation of shear force and bending moment along the length of the beam.

• Shear force is the force that acts perpendicular to the longitudinal axis of the beam.

• Bending moment is the moment that causes the beam to bend.

• In an overhanging beam, one end of the beam extends beyond its support.

• The shear force and bending moment diagram for an overhanging beam will...read more

The stress-strain curve of cast iron shows a distinct yield point.

• Cast iron is a brittle material with a unique stress-strain behavior.

• The stress-strain curve of cast iron typically exhibits a sudden drop in stress after reaching the yield point.

• The yield point is the stress at which the material begins to deform plastically.

• After the yield point, cast iron shows limited ductility and tends to fracture.

• The yield point ...read more

The gas turbine works on the principle of converting the energy of a flowing gas into mechanical energy.

• Gas turbine operates on the Brayton cycle.

• Air is compressed in the compressor section.

• Compressed air is mixed with fuel and ignited in the combustion chamber.

• The hot gases expand through the turbine, driving the turbine blades.

• The turbine is connected to a shaft, which drives the compressor and other equipment.

• Exhaus...read more

Air conditioning and refrigeration are both cooling systems, but differ in scale and purpose.

• Air conditioning is used to cool and dehumidify the air in a room or building.

• Refrigeration is used to cool and preserve perishable items, such as food and medicine.

• Air conditioning systems are typically smaller and focus on maintaining comfort levels for occupants.

• Refrigeration systems are larger and designed to maintain speci...read more

The Joule cycle is a thermodynamic cycle that represents the operation of a heat engine.

• The Joule cycle consists of four processes: isentropic compression, constant volume heat addition, isentropic expansion, and constant volume heat rejection.

• It is often used to model the operation of gas turbines and internal combustion engines.

• The cycle assumes idealized conditions and serves as a theoretical framework for analyzing...read more

Reheat factor is a measure of the efficiency of a gas turbine power plant.

• Reheat factor is the ratio of the actual work output of a gas turbine power plant to the work output if the same amount of heat is added at constant pressure.

• It indicates how effectively the heat is converted into useful work.

• A higher reheat factor indicates a more efficient power plant.

• Reheat factor can be calculated using the formula: Reheat Fa...read more

Cutoff ratio is the ratio of the cylinder volume at the end of the compression stroke to the clearance volume.

• Cutoff ratio is an important parameter in internal combustion engines.

• It determines the compression ratio and affects the engine's efficiency and power output.

• A higher cutoff ratio leads to a higher compression ratio, resulting in better combustion and increased efficiency.

• Cutoff ratio can be calculated by divi...read more

A compressor is a mechanical device that increases the pressure of a gas by reducing its volume.

• Compressors are widely used in various industries, including manufacturing, oil and gas, and refrigeration.

• There are two main types of compressors: positive displacement compressors and dynamic compressors.

• Positive displacement compressors work by trapping a volume of gas and then reducing its volume to increase the pressure...read more

Pressure ratio is the ratio of the outlet pressure to the inlet pressure in a fluid system.

• Pressure ratio is a measure of the change in pressure across a system.

• It is calculated by dividing the outlet pressure by the inlet pressure.

• Pressure ratio is commonly used in engineering applications, such as in compressors and turbines.

• A high pressure ratio indicates a significant increase in pressure, while a low pressure rati...read more

Axial compressors have a flow path parallel to the axis, while centrifugal compressors have a flow path perpendicular to the axis.

• Axial compressors have a higher flow rate and lower pressure ratio compared to centrifugal compressors.

• Axial compressors are used in applications where a large volume of air needs to be compressed, such as jet engines.

• Centrifugal compressors are used in applications where a higher pressure r...read more
