Forces
A squeezing or squishing force.
What is compression?
Flat structure supported at each end.
What is a beam?
A non-moving, non-changing load
What is a static load?
The type of support when you make a material thicker.
What is lamination?
A force that occurs when the surfaces of two objects move against each other.
What is friction?
Wringing out a wet towel demonstrates this type of force.
What is torsion?
A structure composed of several triangular shapes.
What is a truss?
a load that moves or changes over time
What is a dynamic load?
If parts are carefully shaped, they can hold themselves together.
What is a interlocking shapes?
A joint that does not move. It is intended to keep the structure rigid.
What is a fixed joint?
Scissors cutting paper demonstrates this type of force.
What is shear?
Frame structures are made up of this.
What is a combination of parts?
A force applied to the structure by something else.
What is external forces?
Type of strengthening used in packaging.
What is corrugation?
A joint that allows the structure to move at certain points.
What is a mobile joint?
Two or more distinct elements, energies, or factors that work together, enhancing each other to create a stronger, balanced, or complete whole.
What is complementary force?
One advantage of a frame structure over a solid structure is this.
What is they use less material and are lighter?
A force that one part of the structure exerts on another part of the same structure - in other words, the forces within the structure.
What is internal force?
Used in construction. Make permanent holes in material being joined. Holes can cause weakening of material.
What is a nail, screw, or rivet?
Found at the ends of some bones, where it reduces friction, provides smooth movement, and helps absorb shock when bones bump together.
What is cartilage?
A person standing on a beam bridge causes this type of force to the top of the bridge.
What is compression?
Strong because the force of the load is spread out across the arch to the foundation.
What is a arch?
If a structure is supported at its ________ ___ _________, it will remain balanced.
What is the centre of gravity?
__________ require the force of friction to work!
What is a joint?
It is a structure composed of several layers of different materials. Each layer of material has a specific job to do to maintain the strength and stability
What is a tree?
