The study of energy, heat, and work.
Multiple choice: Which of the following is a key principle of fluid mechanics? A) Bernoulli’s principle B) Newton’s second law C) Hooke’s law
A) Bernoulli’s principle
What is the purpose of a heat exchanger?
To transfer heat between two or more fluids.
True or False: The laws of thermodynamics include the law of conservation of energy.
True
What does CAD stand for in mechanical engineering?
Computer-Aided Design
Fill in the blank: The study of how forces affect motion is known as _______.
Dynamics
What is the significance of the Reynolds number?
It predicts flow patterns in different fluid flow situations.
Multiple choice: Which material property describes a material’s ability to deform under stress? A) Elasticity B) Density C) Thermal conductivity
A) Elasticity
What is the principle of conservation of momentum?
The total momentum of a closed system remains constant if no external forces act on it.
True or False: Stress is defined as the force applied per unit area.
True
What is the primary use of a gearbox?
To adjust the torque and speed of a mechanical system.
Fill in the blank: The study of the relationship between heat and mechanical work is part of _______.
Thermodynamics
What is a kinematic diagram?
A representation of the motion of mechanical components.
Multiple choice: Which law describes the relationship between pressure, volume, and temperature of a gas? A) Boyle’s Law B) Charles’s Law C) Ideal Gas Law
C) Ideal Gas Law
What does FEA stand for?
Finite Element Analysis
True or False: A pulley is a type of simple machine.
True
What is the primary function of bearings?
To reduce friction between moving parts.
Fill in the blank: The process of designing and analyzing mechanical systems is known as _______.
Mechanical design
What is the role of a mechanical engineer in product development?
To design, test, and oversee the manufacturing of mechanical products.
Multiple choice: Which of the following is NOT a type of mechanical joint? A) Weld B) Bolt C) Circuit
C) Circuit
What is the difference between static and dynamic analysis?
Static analysis deals with loads that do not change over time, while dynamic analysis considers changing loads.
True or False: All mechanical systems are subject to wear and tear.
True
What is the purpose of a mechanical actuator?
