Materials Science
The primary way of joining metals.
What is welding?
The force pulling down on objects.
What is gravity?
The strongest shape.
What is a triangle?
The 4 standard states of matter.
What are solid, liquid, gas, and plasma?
Similar to the amount of water flowing through a pipe, this measures the charge flowing per second.
What is current?
Stronger than metals, this group of materials includes crystals, clay, and glass.
What are ceramics?
One of the basic mechanisms, these transfer rotational speed into torque or vice versa.
A giant ball at the top of a building which counteracts swaying.
What is a tuned mass damper?
A law relating pressure, temperature, volume, and number of molecules of an ideal gas.
What is the ideal gas law?
Similar to the pressure in a water pipe, this is the difference in charge between two points.
What is voltage (or potential difference)?
One of the components of elasticity, this quantity is the force on an object divided by the area of it.
What is engineering stress?
A device that converts rotational motion into electricity.
What is a generator?
The practice of having backup systems for fracture-critical members.
What is critical redundancy?
The temperature at which all movement ceases.
What is absolute zero (or 0 K?)
The name for a material that doesn't allow current to flow easily.
What is an insulator?
This is a measure of material strength, or how much force it withstands before deforming.
What is Young's Modulus (or Elasticity?)
The branch of mechanical engineering that builds robots.
What is mechatronics?
A framework, typically consisting of beams or poles, that distributes the load throughout a structure.
What is a truss?
A law that says that a heat engine can never produce more power than it receives, and heat always flows from hot to cold.
What is the second law of thermodynamics?
A basic circuit element, these store energy as a voltage between two parallel plates.
What is a capacitor?
A manufacturing method, this pushes liquid metal or plastic through a mold, providing long parts with uniform cross-section.
What is extrusion?
A thermodynamic device that transfers pressure in a fluid into speed. (Hint: These are seen on spray bottles.)
What is a nozzle?
A seismic design element, this solid, reinforced wall transfers sideways force (shear) into the ground.
What is a shear wall?
A type of force in a fluid that resists all movement and causes turbulence.
What is viscosity?
The circuit component that stores energy by magnetic field.
What is an inductor?
