Science
Question | Answer |
---|---|
What is a Structure? | Anything made of parts put together for a particular purpose (or purposes.) |
What is the difference between Form and Function? | Form is the shape and physical appearance of a structure, while function is the task or purpose of a structure. |
What is a Force? | A push or a Pull. |
What is the Definition of Gravity? | The force of attraction between all objects. |
What is the difference between applied and non-contact forces? | Non-contact force is forces that push or pull without contact, while applied force is when two objects come into contact. |
What is the difference between mass and weight? | Mass is the quantity of matter in an object, while weight is the force of gravity acting downward on an object. |
What is the difference between dead, live, and dynamic loads? | Dead load is the weight of the structure itself, a live load is the weight of the objects that a structure supports, and a dynamic load is a load that's caused by forces other than gravity. |
What is a solid structure? | An object that uses solid construction. |
What is a frame structure? | A network of parts that supports loads. |
What is a shell structure? | A hollow structure with a curved shape. |
What instrument/unit is used to measure mass and weight? | Mass uses balance and grams, while weight uses the newton spring scale and Newtons. |
What is the difference between internal and external forces? | An internal force is acting between two parts of a body, while an external force is a force acting on a structure from the outside. |
What is the point of application? | The point of application is the location of an object, where the force is applied. |
What is the plane of application? | The plane of application is an imaginary flat surface through the force passes. |
What is compression? | An internal force that presses or squeezes the particles of an object together. |
What is torsion? | Internal twisting forces created in an object as a result of a twisting motion being applied to the object. |
What is tension? | An internal force pulling the particles of an object apart. |
What is shear? | Forces acting in an object as a result of pushes and/or pulls in opposite directions; usually resulting in rips or tears of an object. |
