Difference between Datum and Datum feature is<em> 'Datum is theoretical and Datum feature is real'.
</em>
Option: (b)
<u>Explanation:</u>
A Datum is a perfect plane, line, point or surface but only occurs theoretically.
However a Datum Feature is fully based on a tangible surface, axis or point on a part where that theoretical datum is located.
The reason behind in this is they are not equal to each other because the 'part surface' is never 100% perfect.
The important functional features of the Datum is controlled during measurements.
Answer: The movement of tectonic plates
Explanation:
Tectonic plates are the part of the earth's crust that both the ocean and land rest on. These plates are constantly moving as a result of currents in the mantle.
These movements cause stress on the surface which has the effect of fracturing rocks and thereby creating/ forming faults in the earth's crust. Sometimes faults form when these plates move away from each other and sometimes they are formed when they push into each other.
The three previous manufacturing revolutions that Mr. Scalabre mentioned and their year of occurrence are:
- The steam engine in the mid-19th Century
- The mass-production model in the early 20th Century
- The first automation wave in the 1970s
<h3>What is a Manufacturing Revolution?</h3>
This refers to the process of change from a handicraft economy to industry production-based production.
Hence, we can see that Mr. Scalabre believes we are not growing in productivity because there has not been enough automation to perform the tasks needed.
The effect of robotics is making an impact on productivity because a lot of complex, difficult tasks are done by machines.
3D printing has made an impact on productivity because there is a reduction in the pressing cycle and errors due to negligence are reduced.
The role the engineers have to play in the next revolution is that they would have to produce mathematical model that can be used to produce better AIs

Answer:
F₁ = 1500 N
F₂ = 750 N
= 500 N
Explanation:
Given :
Power transmission, P = 7.5 kW
= 7.5 x 1000 W
= 7500 W
Belt velocity, V = 10 m/s
F₁ = 2 F₂
Now we know from power transmission equation
P = ( F₁ - F₂ ) x V
7500 = ( F₁ - F₂ ) x 10
750 = F₁ - F₂
750 = 2 F₂ - F₂ ( ∵F₁ = 2 F₂ )
∴F₂ = 750 N
Now F₁ = 2 F₂
F₁ = 2 x F₂
F₁ = 2 x 750
F₁ = 1500 N , this is the maximum force.
Therefore we know,
= 3 x
where is centrifugal force
= / 3
= 1500 / 3
= 500 N
