Answer: The engineer will create a detailed sketch that labels all of the visual components.
Explanation:
It should be noted that the reverse engineering is required for the replacement and the modification of an existing product.
With regards to the question, the correct answer is option A "The engineer will create a detailed sketch that labels all of the visual components".
Answer:
Explanation:
For this case we have given the following data:
represent the temperature for the air
represent the velocity of the air
represent the specific heat ratio at the room
represent the gas constant for the air
And we want to find the velocity of the air under these conditions.
We can calculate the spped of the sound with the Newton-Laplace Equation given by this equation:
Where K = is the Bulk Modulus of air, k is the adiabatic index of air= 1.4, R = the gas constant for the air, 
the density of the air and T the temperature in K
So on this case we can replace and we got:
The Mach number by definition is "a dimensionless quantity representing the ratio of flow velocity past a boundary to the local speed of sound" and is defined as:
Where v is the flow velocity and 
the volocity of the sound in the medium and if we replace we got:
And since the Ma<0.8 we can classify the regime as subsonic.
Answer & Explanation:
"The force <em>on a cutting tool</em> are 2600N vertically downward" sounds a little unusual, since most of the time, the tool is above the object to be cut in such a way that the force acting "ON the tool" is upwards. We will accept the statement as it is (downwards).
Since the two forces are acting at right angles to each other, the resultant can be found using Pythagoras theorem, namely
resultant = sqrt(2600^2+2100^2) = 3342 N (approx.)
The angle can be found using the arcTangent function, or
angle = arcTangent(2600/2100) = 51.07 degrees below the horizontal, since the 2600 N force is acting downwards.
