If you build medical machines, what type of engineer are you?
A biomedical engineer.
What is a tunnel?
An artificial underground passage, especially one built through a hill or under a building, road, or river.
What is a catapult and trebuchet used for?
A catapult is a machine used to throw objects.
How many simple machines are there?
Six
Name one type of bridge.
The answer may vary. Possible answer: Pony Truss bridge.
What type of engineer helps make buildings?
1. A civil engineer.
2. An architectural engineer.
Why would you put a foundation under a building?
To make sure it is more stable.
What does a catapult use to power the arm when let go?
Tension and/or torsion
What is a wedge?
An inclined plane used to cut something.
Name all three types of bridges
Pony truss, Deck truss, Through truss.
You meet someone who works in creating planes. What type of engineer is that person?
That person would be an aerospace engineer.
What are the three types of tunnels?
Rock tunnel, soft-ground tunnel, and underwater tunnel.
What are tension and torsion?
Tension is bending an object to make it fling
Torsion is when an object is wrapped around so when it is let go it unravels and springs forward.
What simple machine is used to move an object to a greater height by effort pushing the object up it?
A inclined plane
What catagory is a bridge if it is has squares and half circles that make it up?
A truss bridge.
If you were the maker of bubble gum, what type of engineer are you?
A chemical engineer.
If you were making your own building, what part of the building would you make first?
(Hint: to make sure it is stable...)
A foundation!
When were catapults invented and why were they invented?
They were invented during medieval times and were used to break down castle walls.
Name all six simple machines.
An inclined plane, wedge, screw, wheel and axle, pulley, and lever.
What are the two strongest shapes used in building bridges and towers? Why?
The triangle and the half circle because when the pressure has been applied, they bend not as much as shapes such as the square.
Name at least 11 different types of engineers. (ex. Biomedical...)
A possble answer is..
11 types of engineering are biomedical, civil, structural, electrical, chemical, software, agricultural, computer, aerospace, environmental, and mechanical engineering.
What are impact driven piles?
(Hint: look back to when we were studying the foundation vocab words)
Impact-driven piles - Deep foundation; A driven pile is a relatively long, slender column, provided to offer support or to resist forces, made of preformed material having a predetermined shape and size that can be physically inspected prior to and during installation, which is installed by impact hammering, vibrating or pushing into the earth
What are the differences between trebuchets and catapults
The differences between catapults and trebuchets are that a trebuchet uses a counterweight to help throw an object and a catapult used tension and torsion to throw an object.
Take all six simple machines and put them into there two groups. What are the two groups names?
Inclined plane group: wedge, screw, inclined plane. Lever Group: lever, wheel and axle, pulley.
What is the tallest building in the world?
The Burj Khalifa.
