90 degrees
60 degrees
120 degrees
180 degrees
How many two-dimensional images can be used to represent perpendicular views of an object in multiview orthographic projections?
Up to two
Up to four
Up to six
Up to eight
Which of the following pieces of information is typically included in the title block of an engineering drawing?
The project's overall budget
The designer's name and company logo

What does a scale of 1:1 on an engineering drawing signify?
The object is drawn at half its actual size
The object is drawn at twice its actual size
The object is drawn at its actual size
The object is drawn at a quarter of its actual size
If an engineering drawing has a scale of 1:2, how would you calculate the actual size of the object from a measurement taken directly from the drawing?
Divide the measured dimension by two
Multiply the measured dimension by two
Subtract two from the measured dimension
Add two to the measured dimension
In which type of orthographic projection does the object itself lie between the observer and the projection planes?
Isometric axonometry
Third-angle projection (American projection)
First-angle projection (European projection)
Oblique projection
What does a tolerance of "±0.10" on a 41mm dimension indicate?
The dimension must be exactly 41.00mm.
The dimension can range from 40.90mm to 41.10mm.
The dimension can be 41.00mm or 41.10mm.
The dimension can be 40.90mm or 41.00mm.
What would be the best way to specify a material for a part in the technical drawing?
Aluminum Alloy
Carbon Steel
AISI 304 / SAE 304 stainless steel
Titanium
In a technical drawing, what does a thick continuous line typically represent?
Hidden contours and edges.
Visible contours and edges.
Symmetry axes.
Dimension lines.
What is the primary purpose of a dash-dot line in a technical drawing?
To show hidden features.
To indicate a cutting plane for a section view.
To represent symmetry or center lines for holes.
To define the outer boundary of the object.
What do the 45-degree cross-hatched lines in a section view of a technical drawing represent?
External surfaces of the object.
Internal surfaces of the object that have been cut.
Areas that are not part of the object.
Surface roughness.
How are fillets indicated in a technical drawing's dimensioning?
By a 'Φ' symbol.
By specifying height and angle.
By the letter 'R'.
By a dashed line.
What does "M6" in a threaded hole specification typically indicate according to the ISO standard?
The length of the threaded hole.
The diameter of the hole and the thread.
The pitch of the thread.
The type of material for the thread.
