What type of saw is used to cut wood perpendicular to (across) the wood grain?
Ans: A Crosscut saw
What type of saw is used to cut wood in the direction of the grain?
Ans: A rip saw
A scale on a blueprint indicates 1" = 2". What does this scale mean?
Ans: Each line on the blueprint is shown as half of its actual size
A computerized maintenance management system (CMMS) is a type of ....
Ans: tool
What problems may occur when a person works in a very hot area for a prolonged period of time?
Ans: Heat stroke, Cramps, Exhaustion
What is the purpose of a confined space safety permit?
Ans: 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?
, Page |3
Ans: 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
Ans: FALSE : It does not matter how long it takes to complete a work order, the most
important and integral aspect of your performance when completing a work order is doing it

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?
Ans: 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?
Ans: 1680 lbs/ft
48' * 35lbs = 1680
What is the definition of Arc Welding?
Ans: 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?
Ans: 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?
Ans: An outward force on a mass when it is rotated
How does a positive displacement pump work?
Ans: 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?
Ans: Vacuum pumps have an inlet and and outlet with a nole 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
sidezz
