Trebuchet

What is a "Trebuchet Arm?"

• Essentially a long beam on a pivot that acts as a lever to fling the projectile. 

• Provides support for the device. Often on wheels for mobility.

• Relies on people pulling down on the short end of the arm with ropes.

• :A weight that provides a balance against something of equal weight. It is the “force” for a trebuchet. 

What is a "Counterweight?"

• Holds the projectile in place at the long end of the arm

• Process engineers use to solve problems. 

• A weight that provides a balance against something of equal weight. It is the “force” for a trebuchet.

• Test & redesign is one iteration. Repeat (multiple iterations).

What is "Force?"

• Limitations with material, time, size of team, etc.

• A push or pull on an object. The blank* (counterweight) is much greater than the load (projectile) in a trebuchet.

• A shaft or pin with a pointed end on which something turns.

• The tendency of a turn or twist.

What is a "Fulcrum/Pivot Point?"

• The loss of balance due to an unequal distribution of weight.

• A redirection of counterweight from an unstable base.

• Sling supported beam.

• The point on which a lever rests or is supported and on which it pivots. On a trebuchet, not directly in the middle, as it is on a see-saw.

What is a "Lever?"

• A working model of the solution to be tested.

• A simple machine. A rigid object is used with a fulcrum or pivot point to increase the amount of mechanical force applied to an object.

• Something (such as a bullet or rocket) thrown or shot especially from a weapon.

• The tendency of a force to turn or twist.

What is a "Mechanical Advantage?"

• A point of entry for a pin.

• A removal of interference of outside forces.

• Provides support for the device. Often on wheels for mobility.

• The amount of help you can get by using a simple machine.

What is a "Pivot?"

• An empty void.

• A shaft or pin with a pointed end on which something turns.

• Conditions that the design must satisfy like its overall size, etc

• Last-minute changes to a busy schedule.

What is a "Projectile?"

• Process engineers use to solve problems.

• The speed of Mr. Jackson's lead jab.

• Something (such as a bullet or rocket) thrown or shot especially from a weapon. It is the “load” for a trebuchet.

• The amount of help you can get by using a simple machine.

What is a "Prototype?"

• Relies on people pulling down on the short end of the arm with ropes.

• A final design of a product.

• A working model of the solution to be tested.

• An unstoppable force moving at high speeds.

What is a "Sling?"

• Mixing of the oil to ignite the projectile upon firing.

• An open area from the trebuchet to be fired from.

• Holds the projectile in place at the long end of the arm.
