Analysis of Engineering Information for Mechanical Engineering Course

This assignment solution addresses various engineering concepts, including the tooling required for creating an M8 tapped hole, specifying cutting speeds and feeds for mild steel. It also covers topics such as finding wheel nut torque and gasket material for a BMW 1 Series F20, identifying components in a simple electronic circuit (resistors, capacitors, and diodes) and their operating parameters. The solution further provides details on the wavelength, forward voltage, and other characteristics of a red LED, as well as identifying a supplier and part number for a 3kW electric motor. All the information is supported by relevant references to ensure accuracy and reliability.

Three types of the tooling needed to create an M8 tapped hole
Serial taps and nut taps are used in the performance of tapping. Serial taps are composed of three
or two tools with the design of the cutting part being the distinguishing feature. The entering tap
has trapeziform cutting edges as well as long chamfer and performs about 60% of cutting work.
The plug tap has trapeziform cutting edges and a short chamfer that is deeper and performs about
30% of the cutting task
The finishing tap is composed of cutting edges as well as short chamfer that generates the final
shape of the thread groove, cutting the thread to a nominal size as well as the thread flanks of the
finishes
Nut taps also known as single-pass hand tap joints the cutting segments of the three serial parts.
It thus has a long chamfer accounting for about 70% of the cumulative length of cutting part.
Speeds and feeds of tooling you have decided upon for use in mild steel
The cutting speed is provided as a set of constraints that are available from the supplier or the
manufacturer of the material. The various cutting conditions include dry cutting, the tool life of 1
hour as well as at medium feeds and hence the values are variant depending on the prevailing
conditions
Speed-90ft/min
Feeding determines the speed at which a cutter is fed which is advanced against the workpiece
and is often given in terms of distance for every revolution for boring as well as turning.

Since the cutting speed for tools used for mild steel is 90 ft. /min, the RPM for a3/8” high speed
would be 90*4(3/8) =960 RPM.

The references have been chosen against other sources information since they are up to date with
the required information besides bearing content that is relevant, reliable and significantly
accurate as per the required information. Still, the information contained in these sources bear a
close resemblance to each other with regard to content and hence may be deemed to be more
accurate and reliable in that aspect

Electrical
Identify three typical components you would find in a simple electronic circuit
 Resistor
 Capacitor
 Diodes
Determine two operating parameters of each of the items listed
Temperature coefficient: The resistor value is a factor of the length, resistivity as well as the
cross-sectional area of the resistive material that is used in making it. The variation in the
resistance is a result of the changes in the temperature even though it is often small over a
specific range of temperature.
Frequency response: Resistors are intended to be pure resistors not having any of the features of
other component types which are however not the case with AC circuits which may be bearing
undesirable features. Some of the resistors at high frequencies have features of capacitance as
well as inductance.
Determine the following information for a red LED:
Wavelength-630 to 640 nm
Forward voltage: The forward voltage for an LED is often in the range of between 1.8 and 3.3
volts which is determined by the color of the LED. A red LED ideally drops 1.8 volts even
though since the voltage drop as well as the light frequency increases with an increase in the
band gap, the value changes as the color changes across the board.
Maximum forward current

Physical dimensions
Polarity: This is an indication of the electronic component symmetry. A red LED that is similar
to a PN junction diode is asymmetrical meaning it permits the flow of current in one direction
only.
Forward current: A red LED tends to be quite sensitive to the quantity of current that flows
through it. As the brightness increases, the amount of current drawn also changes. Each LED is
having a rating of the maximum current that is deemed safe to flow through it beyond which it
will blow off.
Forward voltage: This is the characteristic minimal voltage needed to allow the LED to conduct
electricity which is about 20mA for a 5mm red LED even though the forward voltage changes
from an LED to another.
Identify a supplier and part number for a 3kW 220/400 V electric motor
Supplier- FENFA-Dc Drive Motor
Part number-30
