C. It led in a mass migration of African Americans to the Midwest.
Answer:
d. the actual dimensions.
Explanation:
In Engineering, it is a standard and common practice to use drawings and models in the design and development of buildings, tools or systems that are being used for proffering solutions to specific problems in different fields such as banks, medicine, telecommunications and industries.
Hence, an architect or design engineer make use of drawings such as pictorial drawings, sketches, or architectural (technical) drawing to communicate ideas about a plan (design) to others, record and retain informations (ideas) so that they're not forgotten and analyze how different components of a plan (design) work together.
Architectural drawing is mainly implemented with computer-aided design (CAD) software and it's typically used in plans and blueprints that illustrates how to construct a building or an object.
Additionally, architectural drawings such as a section view in a general plan, show in detail how the areas of a building relate to each other, as well as accurately illustrating the actual (true) shape and size of a building in the design and development process.
In dimension drawings, the dimensions written on the drawing are the actual dimensions and the drawings are then made using a scale to reduce the drawing in same proportion.
1.) To find the piston displacement, you have to find the volume of cylinder. The formula for volume is V = pi*r^2*h, where V = volume, r = radius, h = height
2.) V = pi*r^2h
= 3.14*2.25^2*4.5 (bore = diameter; hence r = diameter/2) (height = stroke)
= 3.14*5.06*4.5
= 71.4978 or 71.50
3.) Since the engine has 8 cylinders, multiply the piston displacement by 8
= 71.50*8
= 572
Therefore, the total piston displacement of an 8-cylinder engine is D. 572
