Tensile forces are forces that stretch or pull materials apart.
Tensile forces act in the opposite direction of compressive forces
Examples of tensile forces include stretching a rubber band or pulling on a rope
Tensile strength is a measure of a material's ability to withstand tensile forces
Formulas in Fluid Mechanics
Bernoulli's equation: P + 0.5ρv^2 + ρgh = constant
Continuity equation: A1v1 = A2v2
Navier-Stokes equation: ρ(∂v/∂t + v∇v) = -∇P + μ∇^2v + ρg
Ideal gas law: PV = nRT
Poiseuille's Law: Q = πr^4(ΔP)/(8ηL)
The fundamental laws of thermodynamics govern the behavior of energy in systems.
First Law of Thermodynamics: Energy cannot be created or destroyed, only transferred or converted.
Second Law of Thermodynamics: The entropy of an isolated system will always increase over time.
Third Law of Thermodynamics: As temperature approaches absolute zero, the entropy of a system approaches a minimum value.
Examples: A car engine conve...
Fourier's Law describes the flow of heat through a material.
Fourier's Law states that the rate of heat transfer through a material is directly proportional to the negative gradient of temperature and the area perpendicular to the direction of heat flow.
The equation for Fourier's Law is q = -k * A * (dT/dx), where q is the heat transfer rate, k is the thermal conductivity of the material, A is the cross-sectional area, ...
The Iron-Carbon phase diagram illustrates the phases and microstructures of iron-carbon alloys as a function of temperature and composition.
Shows the phases of iron and carbon at different temperatures and compositions
Includes regions for austenite, ferrite, cementite, and pearlite
Critical points such as eutectic point and eutectoid point are marked
Used to predict the microstructure of steel based on composition and he
The stress-strain curve shows the relationship between stress (force applied) and strain (resulting deformation) in a material.
The curve typically consists of three main regions: elastic deformation, plastic deformation, and fracture.
In the elastic region, the material deforms elastically and returns to its original shape when the stress is removed.
The plastic region is where permanent deformation occurs, but the mater...
SFD and BMD are calculated using equations of equilibrium and relationships between load, shear force, and bending moment.
Calculate reactions at supports using equations of equilibrium
Determine the shear force at different points along the beam by considering the applied loads and reactions
Calculate the bending moment at different points by integrating the shear force diagram
Plot the SFD and BMD based on the calculated...
Velocity of fluid flowing through a pipe can be calculated using the formula Q = A * V, where Q is the flow rate, A is the cross-sectional area of the pipe, and V is the velocity of the fluid.
Calculate the cross-sectional area of the pipe using the formula A = π * r^2, where r is the radius of the pipe.
Determine the flow rate (Q) of the fluid, which is typically measured in cubic meters per second (m^3/s) or liters per...
Entropy is a measure of disorder or randomness in a system, while enthalpy is a measure of the heat energy in a system.
Entropy is a thermodynamic property that measures the amount of energy in a system that is not available to do work.
Enthalpy is a thermodynamic property that measures the total heat content of a system.
Entropy increases in irreversible processes, while enthalpy remains constant.
Entropy is denoted by S,...
The Refrigeration Cycle graph shows the process of cooling a space by transferring heat from inside to outside.
The cycle starts with the refrigerant entering the compressor as a low-pressure gas.
The refrigerant is compressed, raising its temperature and pressure, before entering the condenser where it releases heat to the surroundings.
After losing heat, the refrigerant becomes a high-pressure liquid and flows into the ...
The vapor absorption cycle graph shows the relationship between pressure, temperature, and enthalpy during the process.
The graph typically shows pressure on the y-axis and temperature on the x-axis.
It includes lines representing the various stages of the cycle such as evaporation, absorption, and desorption.
The enthalpy values at different points in the cycle can also be plotted on the graph.
Example: The graph will sho...
The Rankine, Otto, and Diesel cycle graphs are commonly used in thermodynamics to analyze different types of heat engines.
The Rankine cycle is used in steam power plants and consists of four processes: heat addition, isentropic expansion, heat rejection, and isentropic compression.
The Otto cycle is used in spark-ignition engines and consists of four processes: isentropic compression, constant volume heat addition, isen...

BLDC motor stands for Brushless DC motor, which is a type of electric motor that operates without the need for brushes to transfer electrical current.
BLDC motors use electronic commutation instead of brushes to control the motor's operation.
They are more efficient, reliable, and have a longer lifespan compared to brushed DC motors.
BLDC motors are commonly used in applications such as electric vehicles, drones, and indu

Gravity and force theory are two different concepts used to explain the behavior of objects in motion.
Gravity is a fundamental force that attracts objects towards each other.
Force theory suggests that objects in motion will remain in motion unless acted upon by an external force.
Gravity is responsible for the motion of planets around the sun, while force theory explains the motion of a ball rolling down a hill.
Both the...
