Chapter 10 science study

Question 1

Definition of Structure

Answer 1

anything made of parts put together for a particular purpose

Question 2

Definition of function

Answer 2

the task or the purpose of the structure.

Question 3

definition of force

Answer 3

a push or a pull

Question 4

Definition of form

Answer 4

the shape and physical appearance of a structure

Question 5

definition of gravity

Answer 5

the force of attraction between all objects, it is noticeable when at least one of the objects has a large mass, it is a non contact force

Question 6

definition of mass

Answer 6

the quantity of matter, commonly measured as grams (g) or kilograms (kg)

Question 7

definition of weight

Answer 7

the force of gravity acting downward on an object, which is measured in newtons (n)

Question 8

definition of load

Answer 8

force acting on a structure

Question 9

definition of live load

Answer 9

a type of static load caused by the objects itself

Question 10

definition of dead load

Answer 10

a type of static load caused by the weight of the structure itself

Question 11

definition of dynamic load

Answer 11

any load on a structure that is not caused by gravity, for example a car crashing into a building

Question 12

definition of solid structure

Answer 12

an object that uses solid construction to support a load

Question 13

definition of frame structure

Answer 13

a network of parts that support a load

Question 14

definition of shell structure

Answer 14

a hollow structure with a curved shape providing high strength and rigity

Question 15

definition of external forces

Answer 15

a force acting on the outside of a structure or an object

Question 16

definition of internal forces

Answer 16

a force acting between two parts of a body

Question 17

definition of point of application

Answer 17

the location on an object where an external forces is applied or concentrated

Question 18

definition of plane of application

Answer 18

an imaginary flat surface in which an applied force pases

Question 19

definition of tension

Answer 19

an internal force pulling the particles of an object apart

Question 20

definition of compression

Answer 20

an internal force that presses or squeezes thee particles of an object together.

Question 21

definition of torsion

Answer 21

an internal twisting force created in an object as a result of a twisting motion being applied to the object.

Question 21

definition of shear

Answer 21

forces acting on an object as a result as pushes and/or pulls in opposite directions, usually results as rips and tears in an object

Question 22

difference between mass and weight

Answer 22

mass is the amount of matter an object has which is measured in grams or kg, and weight is the gravitational force on an object, which is measured in newtons.

Question 23

difference between Dead load,live load and dynamic load

Answer 23

dead load is the dead load is the object acting on itself, live load is the load that is caused by other weights acting on an object, and dynamic load is not caused by gravity

Question 24

examples of types of structures.

Answer 24

Shell: egg shell Solid: a brick Frame: a ladder

Question 25

difference between internal and external forces

Answer 25

internal forces are forces that act on two parts of a body, and external forces are forces acting on the outside of an object of structure.

Question 26

internal and external forces.

Answer 26

Internal: shear, compression, torsion, and tension. external: gravity, live load, dynamic load and dead load.
