Sample Practice Test Questions

Shop Information

Which of the following is not an advantage of using a tape measure over using a ruler?

measure with more accuracy

Rulers are used to both measure distance and to draw straight lines. Tape measures are flexible rulers useful for measuring longer distances and in tighter spaces. Rulers and tape measures provide similarly accurate measurements.

Electronics Information

Longer the electrical wires mean _______________ voltage drop.


Electrical wires have a certain amount of resistance per foot. A longer wire means more resistance and a greater voltage drop.

Electronics Information

Electrons will flow as current from areas of __________ potential (concentration of electrons) to areas of __________ potential.

high, low

Voltage (V) is the electrical potential difference between two points. Electrons will flow as current from areas of high potential (concentration of electrons) to areas of low potential. Voltage and current are directly proportional in that the higher the voltage applied to a conductor the higher the current that will result.

Mechanical Comprehension

A block and tackle with four pulleys would have a mechanical advantage of:


Two or more pulleys used together constitute a block and tackle which, unlike a fixed pulley, does impart mechanical advantage as a function of the number of pulleys that make up the arrangement.  So, for example, a block and tackle with three pulleys would have a mechanical advantage of three.

Word Knowledge
After the fire, Mrs. Han tried to salvage her family photos from the wreckage.
To save from ruin.
Automotive Information

What is the large casing that contains the cylinders and many of the internal components of the engine?

engine block

The engine (or cylinder) block is the large casing that contains the cylinders and many of the internal components of the engine.

Word Knowledge
The teacher suggested the combative student channel his aggression into boxing.
Eager to fight.
Electronics Information

Which of the following is not true about a line drop?

it is addressed by raising current and lowering voltage across the ransmission line

Electricity is delivered from power stations to customers as AC because it provides a more efficient way to transport electricity over long distances. A line drop is a decrease in voltage between two points on an electrical transmission line due to resistance in the line. A lower current and higher voltage across the line will help compensate for the line drop.

Automotive Information

What does the timing belt do?

synchronizes the camshaft and the crankshaft

Maintaining proper synchronization between the rotation of the camshaft and the rotation of the crankshaft is critical to ensure that the engine's valves open and close at the proper times during each cylinder's intake and exhaust strokes.

Word Knowledge
The stern principal canceled the prom after the seniors played a silly prank.
Harsh, severe.
