When is the only safe time to reach in between the punch & die?
- A.
Never
- B.
When a part is stuck
- C.
When changing tooling
- D.
When the machine is off
Correct Answer
A. NeverExplanation
Reaching in between the punch and die is never safe because it poses a high risk of injury. The punch and die are the components of a machine used for cutting or shaping materials, and they can cause serious harm if someone's hand or any body part gets caught in between them. Therefore, it is always important to avoid reaching in between the punch and die to ensure personal safety.Rate this question:

What does the abreviation "SST" refer to as it applies to sheet metal?
- A.
Carbon Steel
- B.
Stainless Steel
- C.
Aluminum
- D.
Copper
Correct Answer
B. Stainless SteelExplanation
The abbreviation "SST" refers to Stainless Steel when it applies to sheet metal. Stainless steel is a type of steel alloy that contains a minimum of 10.5% chromium, which gives it its corrosion-resistant properties. It is commonly used in various industries, including sheet metal fabrication, due to its durability, strength, and resistance to rust and staining.Rate this question:

What is the degree of a Right Angle?
- A.
90
- B.
180
- C.
270
- D.
360
Correct Answer
A. 90Explanation
A right angle is a type of angle that measures exactly 90 degrees. It is formed when two lines or segments intersect each other at a 90-degree angle. The other options, 180, 270, and 360, are not correct because they represent different types of angles. A 180-degree angle is a straight angle, a 270-degree angle is a reflex angle, and a 360-degree angle is a full rotation or a complete circle. Therefore, the correct answer is 90.Rate this question:

An .03" radius is larger than an .30" radius.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
An .03" radius is smaller than an .30" radius because the number before the decimal point indicates the whole number part of the radius. In this case, 0.03 is smaller than 0.30.Rate this question:

When it applies to sheet metal what does the following symbol refer to?
- A.
Obtuse Angle
- B.
Thru Hole
- C.
Pi
- D.
Acute Angle
Correct Answer
D. Acute AngleExplanation
The symbol "Acute Angle" refers to a type of angle that measures less than 90 degrees. In sheet metal, this symbol is used to indicate a bend or fold in the metal that is less than a right angle. It is important to accurately represent and understand these angles in order to properly fabricate and manipulate sheet metal.Rate this question:

How many sixteenths are in 1/2 inch?
- A.
2
- B.
5
- C.
8
- D.
16
Correct Answer
C. 8Explanation
There are 16 sixteenths in 1 inch. Since the question asks for the number of sixteenths in 1/2 inch, we need to divide the number of sixteenths in 1 inch by 2. Therefore, there are 8 sixteenths in 1/2 inch.Rate this question:

What is the decimal equivalent of 3/4 of an inch?
- A.
.380
- B.
.075
- C.
7.50
- D.
.750
Correct Answer
D. .750Explanation
The decimal equivalent of 3/4 of an inch is .750. This is because when we divide 3 by 4, we get 0.75. In decimal form, this is written as .750.Rate this question:

What measuring device is used to measure as angled bend?
- A.
Protractor
- B.
Tape Measure
- C.
Calculator
- D.
Screwdriver
Correct Answer
A. ProtractorExplanation
A protractor is a measuring device specifically designed to measure angles and bends. It consists of a semicircular or circular disc with marked degrees and a pivoting arm or needle that can be aligned with the angle being measured. A protractor is commonly used in geometry, construction, and engineering to accurately measure and draw angles. Therefore, a protractor is the correct device to use when measuring an angled bend.Rate this question:

All metals will bend the same under similar conditions.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
This statement is false because different metals have different levels of malleability, which determines their ability to bend under similar conditions. Some metals like aluminum are highly malleable and can be easily bent, while others like steel are less malleable and require more force to bend. Therefore, all metals do not bend the same under similar conditions.Rate this question:
