The first part of the exam consists of twenty-four questions from which the candidate must answer correctly. These questions cover topics such as the relationship between a lubricant and a fluid, the difference between a lubricant and a solvent, the effects of temperature on lubrication, the concept of creep and its effects on friction, the concept of a fluid’s viscosity and the concepts of heat transfer and visco-elasticity. The second part of the exam consists of thirty-two questions that must be answered correctly to pass the exam. These questions include:
The physical aspects of the design of a machine are a major part of the exam. Students must know how to determine the force required to lift a heavy piece of equipment; how to calculate the speed of the machine and the power required to operate it; how to estimate the strain that the machine will encounter; how to calculate the force required to move a single point on a large object; how to determine the tension needed to keep a piece of equipment running smoothly; and how to calculate the weight that the machine will have when the drive belt is removed. Students must also be able to describe in layman’s terms the process by which a fluid passes through a pipe orifice, as well as the flow characteristics of a gas.
When students fail the test, the examiner can determine the student’s knowledge by determining what knowledge they possessed in high school and college. If the student has not taken any mechanical engineering courses before the exam, he or she must pass with a grade of C or better.
The materials used in the mechanics exam are used to test a student’s understanding of all areas of mechanical engineering. The topics covered in this portion of the exam include: the properties of metals, oils, fluids, and ceramics, as well as mechanical machines. The physical properties of metals include their melting points, tensile strength, ductility, and wear resistance.
The concepts of fluids are used in the exam to determine a student’s knowledge of all aspects of mechanical engineering, including mechanics, electrical engineering, and thermodynamics. The topics covered in the course include the mechanics of heat transfer, fluid mechanics, heat transfer, and energy, and mechanics of fluids and ceramics. The concepts of thermodynamics include their transfer and distribution. A student must also demonstrate their knowledge of the theory of heat transfer and its effect on heat transfer as well as their properties. The concepts of thermodynamics include the concept of universal thermodynamics and the law of energy.
Mechanical engineers also need to take the concepts of mechanics into consideration when answering the question of how a system works. Students need to be able to describe the principles of mechanics, which includes the following: reciprocating motion, angular and lateral motion, the conservation of energy, the first and third laws of mechanics, the law of conservation of momentum, the law of conservation of energy and dynamics. They also need to be able to describe the theory of mechanics and the forces that act upon the system when it is moving.
The mechanics exam is designed to assess the knowledge of a mechanical engineer. It also involves several simulations and exercises, such as the use of physical models, a combination of real and digital laboratory work, and computer-based procedures. Students should be aware of the concepts of mechanics, which include the first three laws of mechanics, the concepts of mechanics of fluid mechanics, and the theory of mechanics.
