manufacturing process is and provide

an example.

$200 Manufacturing

Subtractive processes remove

material from a part or object.

examples include drilling, milling,

cutting.

$300 Manufacturing

What three factors determine the

selection of a material for

manufacturing purposes?

$300 Manufacturing

Material selection is based on:

1) application,

2) material properties needed,

3) budget.

$400 Manufacturing

What type of manufacturing shop

produces a large variety of products in

small quantities?

$400 Manufacturing

Job Shop

$500 Manufacturing

The type of shop that uses an

assembly-line method to build cars and

What is the significance or the 3

arrows in the recycling symbol –

what do they stand for?

$100 Recycling

The first arrow represents the consumer gathering the

recyclable materials to be recycled.

The second arrow represents the manufacturer

recycling the materials to create new products.

The third arrow represents the consumer buying

products made from recycled materials.

$200 Recycling

What does the number in the recycling

triangle mean?

$200 Recycling

It indicates the type of resin or

plastic that is used to create the

recyclable product.

$300 Recycling

Provide 2 specific examples of recycling

organic materials, including the original

material and a recycled application.

$300 Recycling

Paper – recycled to make new paper.

Yard Waste – recycled to make mulch or

pet bedding.

cross-sectional area in material testing.

$100 Key Words

Stress

$200 Key Words

The ratio of stress to strain in material

testing. Also, defines the stiffness of an

object based on its composition and/or

chemical properties.

$200 Key Words

Modulus of Elasticity

$300 Key Words

The change in length of a material or

object in some direction, per unit of

original length.

$300 Key Words

Strain

$400 Key Words

During material tensile testing, the point

at which the deformation is no longer

proportional to the applied force.

$400 Key Words

Proportional limit

$500 Key Words

The maximum stress that a material can

withstand without permanent

deformation.

$500 Key Words
