    What is hydraulics? 

    • A topic in applied science and engineering dealing with the properties of water.

    • A topic in applied science and engineering dealing with the mechanical properties of liquid fluids.

    • A topic in applied science and engineering dealing with the energetic properties of matter.

    • A topic in psychology dealing with the fear of water.

    Correct Answer
    A. A topic in applied science and engineering dealing with the mechanical properties of liquid fluids.
    Explanation
    Hydraulics is a topic in applied science and engineering that focuses on the mechanical properties of liquid fluids. It involves the study of how liquids behave under pressure and how they can be used to transmit force and energy. This field is essential in various industries, such as construction, automotive, and aerospace, where hydraulic systems are used for power transmission and control. Understanding the mechanical properties of liquid fluids is crucial for designing and maintaining efficient and reliable hydraulic systems.

    What is the most fundamental principle in fluid power? 

    • Newton's Law

    • Gauss's Law

    • Pascal's Law

    • David's Law

    Correct Answer
    A. Pascal's Law
    Explanation
    Pascal's Law is the most fundamental principle in fluid power. It states that when pressure is applied to a fluid in an enclosed space, the pressure is transmitted equally in all directions. This principle is the foundation for many applications of fluid power, such as hydraulic systems, where pressure is used to transmit force and control motion. Pascal's Law allows for the amplification of force, making it a crucial principle in the field of fluid power.

    Rate this question:

  • 4. 

    Pascal's Law states that: 

    • The pressure exerted on one side of a confined fluid equals half the pressure exerted on the opposing side.

    • The pressure exerted on a confined fluid is transmitted undiminished in all directions and acts at right angles to the containing surfaces.

    • The pressure exerted on an open fluid is transmitted undiminished in all directions and acts at right angles to the containing surfaces

    • Pressure is as pressure does.

    Correct Answer
    A. The pressure exerted on a confined fluid is transmitted undiminished in all directions and acts at right angles to the containing surfaces.
    Explanation
    Pascal's Law states that the pressure exerted on a confined fluid is transmitted undiminished in all directions and acts at right angles to the containing surfaces. This means that when pressure is applied to a fluid in a closed container, the pressure is evenly distributed throughout the fluid and is transmitted to all parts of the container. The pressure is not reduced or diminished as it is transmitted, and it acts perpendicular to the surfaces of the container. This principle is the basis for many hydraulic systems and is important in understanding fluid mechanics.

    Is an unconnected battery an example of potential or kinetic energy?

    • Potential

    • Kinetic

    Correct Answer
    A. Potential
    Explanation
    An unconnected battery is an example of potential energy because it has the ability to store energy and convert it into a different form of energy, such as electrical energy, when connected to a circuit. The potential energy is stored in the chemical compounds within the battery, which can be converted into electrical energy when the battery is connected to a device or a circuit.

    Which correctly relates pressure (P), force (F), and area (A)?

    • P = FA

    • P = A/F

    • P = AF^2

    • P = F/A

    Correct Answer
    A. P = F/A
    Explanation
    The correct equation that relates pressure (P), force (F), and area (A) is P = F/A. This equation states that pressure is equal to the force applied divided by the area over which the force is applied. In other words, pressure is directly proportional to force and inversely proportional to area. When the force applied is larger, the pressure exerted will also be larger, while increasing the area over which the force is applied will decrease the pressure.

    What is the law of conservation of energy?

    • F = ma

    • Energy is almost always conserved

    • Energy can be neither created nor destroyed

    • Energy is conserved, except when friction is involved

    Correct Answer
    A. Energy can be neither created nor destroyed
    Explanation
    The law of conservation of energy states that energy cannot be created or destroyed, but it can only be transferred or transformed from one form to another. This principle is based on the understanding that energy is a fundamental property of the universe and is always conserved in any physical process. Therefore, the correct answer is "Energy can be neither created nor destroyed."

    Which of the following area formulas for a piston is correct? (Approximate pi)

    • A = (3.14D^2)/2

    • A = (3.14D^2)/4

    • A = (3.14D^3)/4

    • A= (3.14D^4)/2

    Correct Answer
    A. A = (3.14D^2)/4
    Explanation
    The correct formula for finding the area of a piston is A = (3.14D^2)/4. This formula is derived from the formula for the area of a circle, which is A = πr^2. In this case, the diameter (D) of the piston is used instead of the radius (r). To find the area, we square the diameter and divide it by 4, multiplied by π (approximately 3.14). This formula gives us the correct calculation for the area of the piston.

    What is a force? 

    • Any influence capably of producing a change in the motion of a body

    • The mass of an object times its velocity

    • The energy transferred from one object to another

    • Something Luke uses to bring peace to the galaxy

    Correct Answer
    A. Any influence capably of producing a change in the motion of a body
    Explanation
    The correct answer is "Any influence capably of producing a change in the motion of a body." This definition accurately describes what a force is - it is a push or pull that can cause an object to move, accelerate, or change direction. Forces can be exerted by any object or substance, and they can have various magnitudes and directions. This definition encompasses the fundamental concept of force and its effect on the motion of objects.

    Which are examples of resistance? (More than one correct answer) 

    • Friction

    • Work

    • Inertia

    • Velocity

    Correct Answer(s)
    A. Friction
    A. Inertia
    Explanation
    Friction and inertia are examples of resistance because they both oppose the motion of an object. Friction is the resistance that occurs when two surfaces rub against each other, while inertia is the resistance an object has to changes in its motion. Both of these examples demonstrate how resistance can act against the force or motion of an object.
