Material Properties

ENGR JC 2ND YR

QuestionAnswer
What are the 5 engineering forces Tension, Compression, Shear, Bending and Torsion.
What is tension Tensile strength is the maximum pulling force a material can withstand before breaking. Cables and chains need to have this property. Like Resistance bands
What is compression Compressive strength is the ability of a material to withstand squashing or compressive forces. Like a Hydraulic press
What is a Shear force Shear strength is the ability of a material to withstand cutting forces. Like a Scissors cutting
What is a bending Bending strength is the ability to resist bending forces. Like 3d Printed build plate
What is Torsion Torsional strength is the ability to withstand a twisting force or torsion. Like a Salt grinder motion
What is strength The ability of a material to withstand forces.
What is hardness The ability of a material to resist wear, indentation and scratching.
What is ductility The ability of a material to be permanently stretched without fracture by a tensile force.
What is malleability The ability of a material to be extended in all directions without rupture by rolling or hammering. You can increase the malleability of a material by heating it.
What is toughness The ability of a material to withstand blows or impacts.
What is Brittleness This is the opposite to toughness. A brittle material can easily be fractured by an impact.
What is Elasticity The ability of a material to return to its original shape when freed from the force that was distorting it.
What is Plasticity The ability of a material to be permanently deformed without fracturing. Heating the material will improve its plasticity.
What is conductivity The ability of a material to allow heat or electricity flow through it.

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
