B) Float
When the water level rises past the safe area, the float turns on the sump
pump. When the lever of water in the sump pump goes down, the float
also goes down and will shut off the sump pump.
Extra Note: Sump pumps are devices that are placed in a basement
designed to pump out excess water that would otherwise cause
significant flooding. They are almost always put in the lowest point in
the floor and often placed in their own specially dug pit.
Automatic operation of a sump pump is controlled by the

B) Float
C) Foot Valve
D) Centrifugal Driving Unit

are connected to a yolk around the center bar, this outward motion pulls
the balls upward.
The figure above shows a governor on a rotating shaft. As the shaft
speeds up, the governor balls will move
A) Down
B) Upward and Inward
C) Upward
D) Inward
B) 3/4 turn
The piston is now in part of the compression stroke; 1/4 turn will move
it to full compression; 1/2 more turn will move it to the end of the power
stroke. Adding 1/4 + 1/2 = 3/4 turn.
The figure above shows a crank and piston. The piston moves from
midposition to the extreme right if the crank makes
A) 1/2 turn
B) 3/4 turn
C) 1 turn
D) 1 1/2 turns

C) If the head of the bolt is stationary and the nut is turned clockwise,
the nut will move up.
To tighten the bolt, turn it counter-clockwise. To tighten the nut on the
bolt the reverse is true, turn it clockwise.
Referring to the figure above, which one of the following statements is
true?
A) If the nut is held stationary and the head is turned clockwise, the bolt
will move down.
B) If the head of the bolt is held stationary and the nut is turned
clockwise, the nut will move down.
C) If the head of the bolt is stationary and the nut is turned clockwise,
the nut will move up.
D) If the nut is held stationary and the head turned counter-clockwise,
the bolt will move up.
