In terms of lubrication, what is required for a sealed ball bearing? - ANSWER It does not
need to be lubricated under normal use
What is the purpose of a breakaway switch? - ANSWER To apply the breaks on a trailer in
the event of a trailer release from a vehicle
What type of saw is used to cut metallic materials? - ANSWER Hacksaw
What type of saw is used to cut intricate external shapes and interior cut-outs in woodworking
and carpentry? - ANSWER A coping saw
What type of saw is used to cut wood perpendicular to (across) the wood grain? - ANSWER
A Crosscut saw
What type of saw is used to cut wood in the direction of the grain? - ANSWER A rip saw
A scale on a blueprint indicates 1" = 2". What does this scale mean? - ANSWER Each line on
the blueprint is shown as half of its actual size
,A computerized maintenance management system (CMMS) is a type of .... - ANSWER tool
What problems may occur when a person works in a very hot area for a prolonged period of
time? - ANSWER Heat stroke, Cramps, Exhaustion
What is the purpose of a confined space safety permit? - ANSWER It ensures the use of
safety precautions and use of standard safety procedures when working in a confined space
Why must preventative maintenance tasks be documented? - ANSWER Records are needed
to show the type and frequency of maintenance of operating units and to evaluate the
effectiveness of maintenance programs
True or False : When accepting a work order, the need for speedy completion is an integral
aspect of your performance as a Maintainenance Technologist - ANSWER FALSE : It does not
matter how long it takes to complete a work order, the most important and integral aspect of

There is an 18" wide red stripe painted on the ground around a tank. The tank is 25' high and
150' in diameter. What is the perimeter on the outer edge of the stripe? - ANSWER 475.71 ft
18" = 1.5'
Perimeter = Diameter * pi = (150' + 1.5') * 3.14 = 475.71
A 12" diameter pipe, 48' long, weighs 35lbs per linear ft. What is the weight of the total load? -
ANSWER 1680 lbs/ft
48' * 35lbs = 1680
, What is the definition of Arc Welding? - ANSWER Arc Welding is a welding process that is
used to join metal to metal by using electricity to create enough heat to melt metal, and the
melted metals, when cool, result in a binding of the metals
How does a centrifugal pump work? - ANSWER Moves fluid by means of rotational energy
from rotor drives/impellers. Fluid enters the rapidly rotating impeller along its axis and is cast
out by centrifugal force along its circumference through the impeller's vein tips
What is centrifugal force? - ANSWER An outward force on a mass when it is rotated
How does a positive displacement pump work? - ANSWER Pump moves fluid by repeatedly
enclosing a fixed volume of fluid, with the aid of seals or valves, and moving it mechanically
(with a piston or a plunger) through a system
How does a vacuum pump work? - ANSWER Vacuum pumps have an inlet and and outlet
with a nozzle in between - the nozzle restricts flow of fluids, thereby increasing fluid's velocity
and decreases the fluids pressure. A vacuum is created by the lack of pressure which pulls the
fluid into the nozzle and forces it out the other side
What types of coatings are usually used on the inside of wet wells? - ANSWER Epoxy
coatings
What is a wet well? - ANSWER A tank, a portion of a water system that temporarily stores
water before it is pumped elsewhere
What does "galvanized" mean? - ANSWER Coated with a protective layer of zinc
What does PVC stand for? - ANSWER Polyvinyl chloride, a type of plastic used for pipes
