Atom and Eve
This central part of an atom contains protons and neutrons.
What is the nucleus?
This company-floor device replaces relay logic and automates machines with programmed instructions.
What is a PLC?
Bearings reduce this type of resistance between moving parts.
What is friction?
This invisible force is produced by moving electric charges and can attract or repel magnetic materials.
What is a magnetic field?
This device converts electrical energy into mechanical motion.
What is an electric motor?
These negatively charged particles orbit the nucleus.
What are electrons?
This common PLC programming language looks like electrical schematics and uses rungs and contacts.
What is ladder logic?
This popular bearing type uses small hardened spheres to support radial loads with low friction.
What is a ball bearing?
This component, often a coil of wire, generates a magnetic field when current passes through it.
What is a solenoid?
This motor type uses a rotating magnetic field in the stator and does not require brushes.
What is an induction motor?
An element’s identity is determined by this number, equal to its count of protons.
What is the atomic number?
A PLC reads sensors through these types of modules, which include digital and analog versions.
What are input modules?
Thrust bearings are designed primarily to handle forces in this direction.
What is axial?
A short burst of electrical energy used to transmit signals or trigger devices is called this.
What is a pulse?
In a motor, this part rotates and interacts with the magnetic field to produce torque.
What is the rotor?
Atoms of the same element with different numbers of neutrons are known as these.
What are isotopes?
During its scan cycle, a PLC updates outputs only after completing this stage, following reading inputs and executing logic.
What is the update/output stage?
These bearings, often made of bronze, rely on a thin film of oil rather than rolling elements.
What are plain (or sleeve) bearings?
According to Faraday’s Law, a changing magnetic field induces this in a nearby conductor.
What is an electric current?
This device or method adjusts motor speed by varying the voltage or frequency supplied.
What is a variable frequency drive (VFD)?
The outermost electrons in an atom, involved in bonding, are called these.
What are valence electrons?
These types of PLC memory locations, often labeled as bits, integers, or floats, store real-time process information.
What are data registers?
This special type of bearing can tolerate shaft misalignment using an inner ring that tilts within the outer ring.
What is a spherical roller bearing?
These devices store energy in a magnetic field and release it in pulses, often used in radar and switching power supplies.
What are inductors or magnetic pulse generators?
These motors are powered by direct current and use brushes to transfer current to the rotor.
What are DC brushed motors?
