Series circuit
circuit that has one path for the current to flow.
Parallel circuit
circuit that has more than one path path for the current to go through.
Flat key
Key that fits into keyways in both the shaft and the secured member in machinery
Square key
Most common have a square or rectangular cross section
Woodruff key
Are semicircular fits partially into a circular segment keyway
,Plain Tapered keys
Is tapered only on the side that engages the hub the keyway has a tapered keyway
Rounded keys
These keys are used for the large heavy duty shafts
Big head key
A key for securing a member to a machine shaft that fits into a keyway in the secured member
and its concave to grip the shaft by friction
Ball bearings
Type of rolling element bearing that uses balls to maintain the separation between the
bearing races
Roller bearings
Type of rolling element bearing that uses cylinders to maintain the separation between
moving parts and the balls
Ball thrust bearing
Is a type of rotary ball bearing it permits rotation between parts but they are designed to
support a high axel load
,Taper rolling bearings
Have tapered inner and outer ring raceways as well as tapered rollers designed to
accommodate combined loads simultaneously acting radicals and axial loads
Magnetic bearings
Is a type of bearing that supports a load using magnetic Levitation
Needle bearings
Bearings with cylindrical rollers that are small in diameter relative to their length
Ohms law
V= IxR , R = V/I, I=V/R
Formula for voltage
V=IxR
Formula for Amps
I=V/R
