A___ remote control can be an advantage to an
operator who is welding close to the power source.
•wireless
•corded
•cable technology
•none of these
Answer:
Wireless
Explanation:
A wireless remote control can be an advantage to an operator who is welding close to the power source. Hence, option A is correct.
What is wireless remote control?An electrical device used to wirelessly and remotely operate another device is a remote control, often known as a remote or clicker. Consumer gadgets, such as television sets, DVD players, and other home appliances, can be controlled by a remote control.
In the current electronic market, remote control systems fall into three primary categories: IR-based systems, RD-based systems, and BT-based systems. the receiver and the remote must be lined up exactly for infrared, also known as IR.
IR, on the other hand, is unable to pass through a number of materials but can operate over a much wider spectrum. This allows the user far greater freedom and control in environments with challenging terrain and obstacles.
Thus, option A is correct.

In manufacturing a particular set of motor shafts, only shaft diameters of between 38.20 and 37.50 mm are usable. If the process mean is found to be 37.80 mm with a standard deviation of 0.20 mm, what percentage of the population of manufactured shafts are usable?
Answer:
we can conclude that 91.04% population of shafts are usable
Explanation:
Given that;
X[tex]_{min}[/tex] = 37.50 mm
X[tex]_{max}[/tex] = 38.20 mm
mean μ = 37.80
standard deviation σ = 0.20 mm
This problem is based on normal probability distribution so, to get the probability, we must calculate; z = x-μ / σ
so;
Z[tex]_{min}[/tex] = (X[tex]_{min}[/tex] - μ) / μ = (37.50 - 37.80) / 0.20 = -1.5
Z[tex]_{max}[/tex] = (X[tex]_{max}[/tex] - μ) / μ = (38.20 - 37.80) / 0.20 = 2
Hence;
P( 37.50 < X < 38.20 ) = P( -1.5 < Z < 2 )
P( 37.50 < X < 38.20 ) = P( 0 < Z < 1.5 ) + P( 0 < Z < 2 )
from the standard normal table table;
P( 37.50 < X < 38.20 ) = 0.4332 + 0.4772
P( 37.50 < X < 38.20 ) = 0.9104 = 91.40%
Hence, we can conclude that 91.04% population of shafts are usable

The in-situ dry density of a sand is 1.72Mg/m3. The maximum and minimum drydensities, determined by standard laboratory tests, are 1.81 and 1.54 Mg/m3,respectively. Determine the relative density of the sand and soil description based on its density.
Answer:
Relative density = 0.7 or 70%
Explanation:
The following information was provided by this question
Pd = 1.72mg/mg³
Pd max = 1.81 mg/mg³
Pd min = 1.54 mg/mg³
We substitute into the formula. This formula is contained in the attachment.
[(1/1.54)-(1/1.72)]/[1/1.54 - 1/1.81]
= 0.649350 - 0.581395 / 0.649350 - 0.552486
= 0.067955/0.096864
= 0.7015
= 0.7
The relative density is Therefore 0.7 or 70% when converted to percentage

Suppose a conventional water bottle cap is made with a single-start thread of 0.125 in pitch. Further suppose that the lid must be rotated 2.75 times to com- pletely close the bottle, requiring the typical use to re-clutch the lid approximately 4 times to screw the lid shut. If the lid is re-designed with exactly the same pitch, but three starts, rather than one, how many times must the lid be rotated to completely close the bottle?
Answer:
11/12 Rev is required to completely close the bottle
Explanation:
Given the data in the question;
pitch = lead = 0.125 inch
total distance moved in 2.75 rotation = 0.125 in × 2.75
Now; Redesigned thread is three (3) start
lead = 3 × pitch = 3 × 0.125 inch
so
Number of turns required = total distance moved / distance moved in one rotation
Number of turns required = total distance / lead
we substitute
Number of turns required = 0.125 in × 2.75 / 3 × 0.125 inch
= 2.75 / 3
= 275 / 300
reduce the numbers ( by dividing the numerator and denominator by 25 )
Number of turns required = 11/12 Rev
Therefore, 11/12 Rev is required to completely close the bottle
