Forces and Load
A push or pull on an object
What is a force
The total weight of the empty bridge structure itself.
What is bridge mass?
What is Newton's 1st law?
Triangle
What is the rigid geometric shape most commonly used to build strong structural trusses?
A push upward, using air and wind to create low air pressure on the wings
What is lift
To stretch or pull on an object.
What is tension?
The maximum amount of weight your bridge can hold safely.
What is maximum load?
Acceleration: The force applied on an object depends on the mass and acceleration of the object
What is Newton's 2nd law?
A deck
What is the roadway of a bridge called?
A force that pulls downward toward earth, using the weight of the plane and its passengers
What is gravity?
To squish or squeeze something, also compress.
What is compression?
What is failure load?
Action/Reaction: Every action has an equal but opposite reaction
What is Newton's 3rd law?
A simple horizontal beam that lays flat and experiences both tension and compression.
What is a beam bridge?
A force that pushes forward, using the power from the Airplane engines
Permanent weight or force on a structure, this includes the bridge road, pillars, cables
What is dead load?
This measures the effectiveness of the bridge by comparing the bridge mass and maximum load.
What is structural efficiency?
Isaac Newton was a famous physicist and mathematician, known for creating the foundational laws of physics
Who was Isaac Newton?
An arch shaped bridge that uses compression to press the arch shape inward and keeps the bridge standing
What is an arch bridge?
A force that pulls backwards, using air, slowing your plane down
What is drag?
Temporary weight or force on a structure, this includes traffic or weather like wind and snow
What is live load?
Weight or force on a structure.
What is load?
The equation for acceleration/Newton's 2nd law
What is F=ma?
A bridge that suspends a roadway in the air using cables to hold it up, being supported with towers, held in tension, keeping the towers in compression
What is a suspension bridge?
What is aerodynamics?
