Question 1

On the CAST mechanical concepts section, if a smaller pulley drives a larger pulley by a belt, what happens to the larger pulley's rotational speed?

Accepted Answer

It rotates slower than the smaller pulley

Answer

A larger driven pulley turns slower than the smaller driving pulley because its greater circumference covers the same belt distance in more time.

Question 2

In the CAST Reading for Information section, what should you do first when answering a question about a passage?

Accepted Answer

Read the question, then locate the relevant text in the passage

Answer

You should identify what the question asks and then find the supporting information directly in the provided passage rather than relying on outside knowledge.

Question 3

The CAST Graphic Arithmetic section primarily tests the ability to do what?

Accepted Answer

Read drawings and perform calculations using the data shown

Answer

Graphic Arithmetic requires extracting numeric values from drawings or diagrams and performing arithmetic to solve practical problems.

Question 4

A gear with 20 teeth meshes with a gear having 40 teeth. For each full turn of the 20-tooth gear, how much does the 40-tooth gear turn?

Accepted Answer

One-half turn

Answer

The larger 40-tooth gear turns half a revolution for each full turn of the smaller 20-tooth gear because it has twice as many teeth.

Question 5

In Mechanical Concepts, which arrangement of a lever gives the greatest mechanical advantage for lifting a load?

Accepted Answer

Effort far from the fulcrum, load close to it

Answer

Placing the effort far from the fulcrum and the load close to it maximizes mechanical advantage, requiring less force to lift the load.
