Understanding Structures and Forces

What does the term "form" refer to in structures?

• The function of a structure

• The shape and physical appearance of a structure

• The weight of a structure

• The material of a structure

What are the two main characteristics of forces?

• Mass and weight

• Form and function

• Magnitude and direction

• Load and structure

What is the definition of mass?

• The force of gravity on an object

• The amount of matter in an object

• The weight of an object

• The size of an object

What is a dead load?

• The weight of the actual structure

• The weight of the object that the structure needs to support

• The force of gravity on an object

• The amount of matter in an object

Which type of structure uses solid materials and is very durable?

• Frame

• Shell

• Solid

• Hollow

What is a characteristic of a frame structure?

• Uses solid materials

• Hollow and curved shape

• Uses a network or skeleton of materials

• Very heavy

What is a characteristic of a shell structure?

• Uses solid materials

• Hollow and curved shape

• Uses a network of materials

• Very heavy

What does tension do in internal forces?

• Presses the particles closer together

• Pulls the particles of a stretched out object

• Increases the weight of an object

• Decreases the mass of an object

What is an example of compression in internal forces?

• Trampoline

• Guitar strings

• Laying on a bed

• Hanging a picture

What is torsion?

• When an object is twisted

• When an object is compressed

• When an object is stretched

• When an object is bent
