Types of Systems
A system with moving parts that work together to transfer force or motion.
What is a mechanical System?
A part of a larger system that works with other parts to help the whole system function.
What is a subsystem?
A rigid bar that pivots around a fulcrum to lift or move a load with less effort.
What is a lever?
The factor by which a machine multiplies the force you apply to it.
What is mechanical advantage?
Using machines or technology to perform tasks without human control.
What is Automation?
A system that uses light to produce an image or help us see.
What is an optical system?
Noise, heat, or waste that is produced but not wanted.
What are side effects (undesired outputs) of a system?
A ramp that lets you move an object upward using less force over a longer distance.
What is inclined plane?
Output force divided by input force.
What is the formula for mechanical advantage?
It reduces errors, completes tasks faster, and can perform dangerous jobs.
What are advantages of automated systems?
A system that uses electricity to power devices.
A device that transfers or changes force and motion to do work.
What is a mechanism?
Splits or cuts objects by pushing force outward is a type of wedge?
What is an Axe or knife
It means the machine makes the task easier by increasing the force applied.
What does it mean if a machine has a mechanical advantage greater than 1?
advantages of self-checkouts at the grocery store
What are Faster transactions, reduced wait times, more privacy, and convenience.
A system created by people to organize society, such as schools or governments.
What is a human-made social system?
Water and sunlight.
What are two inputs a garden needs to grow?
A twisted inclined plane that changes turning motion into lifting or holding force.
What is a screw?
A lever is used to lift a 200 N rock. You apply a force of 50 N. Calculate the Mechanical Advantage.
What is 4?
Mechanical Advantage (MA)=
Input Force/Output Force
=200/50
=4
Using resources in a way that maximizes output and minimizes waste.
What is economic efficiency?
Each member has a role, and they depend on each other.
What is a natural social system?
A mechanism is the part of a subsystem that can... name 2 of the 4 changes?
What are
Change one kind of motion into another
Change one kind of action into another
Change one kind of energy into another
Change one kind of force into another
A pulley system, because it changes the direction of force and can reduce the amount of effort needed to lift a heavy load.
What is a simple machine for lifting a flag up a flagpole,
A nutcracker is a type of what simple machine.
What is a second-class lever?
friction is
What is the force that resists motion when two surfaces rub against each other.
