Answer:
As you might imagine, people working in robotics have strong mathematics, science, programming, and systems analysis skills. But design also plays a big role. Being able to iterate, isolate problems, and prototype until you have just the right design is essential.

Air supplied to a pneumatic system is supplied through the C. Actuator
Explanation
Pneumatic systems are like hydraulic systems, it is just that these systems uses compressed air rather than hydraulic fluid. Pneumatic systems are used widely across the industries. these pneumatic systems needs a constant supply of compressed air to operate. This is provided by an air compressor. The compressor sucks in air at a very high rate from the environment and stores it in a pressurized tank. the Air is supplied thereafter with the help of a actuator valve that is a more sophisticated form of a valve.
From the above statement it is clear that Air supplied to a pneumatic system is supplied through the Actuator
Answer:
(a) 120 kW
(b) 800 kW
Explanation:
Given:
diameter: 1.5 m
length = 22 m
U = 5 m/s
temperature = 20°C
For water at 20°C, take ρ = 998 kg/m³ and µ = 0.001 kg/m⋅s
To find:
power in kW
(a) if the cylinder is parallel
Length / Diameter = L / D = 22 / 1.5 = 14.6 = 15
Re(L) = ρ*U*L / µ = 998 * 5 * 22 / 0.001 = 109780000 = 1.1E8
C(D.Frontal) ≈ 1.1
Force = F = 1.1 * ρ/2 * U² * π / 4 * D
= 1.1 (998 / 2) (5)²(π / 4)(1.5)²
= 1.1 * 499 * 25 * 0.785 * 2.25
= 24000 N
Power = Force * Displacement / time
= F * U
= 24000 * 5
= 120000
Power = 120 kW
b) if the cylinder is normal to the tow direction.
Re(L) = ρ*U*D / µ = 998 * 5 * 1.5 / 0.001 = 7485000 = 7.5E6
C(D.Frontal) ≈ 0.4
Force = F = 0.4 * ρ/2 * U² * D * L
= 0.4 (998 / 2) (5)²(1.5)(22)
= 164670 ≈ 165000
Power = Force * Displacement / time
= F * U
= 165000 * 5 = 825000
≈ 800 kW
Power = 800 kW
Answer:
a
Hardness Test
b
The available hardness test are
- Rockwell hardness test
- Vicker's hardness test
- knoop test
- scratch test
- Brinell hardness test e.t.c
I would suggest Rockwell test because
- It has good accuracy
- In this test loads can be applied in 2 stages hence better results are obtained
- it saves time because it testing are faster
c
Well the following would be the reasons for low hardness value
- It could be because the steel used has a low percentage of carbon
- it could also result from the quenching medium used (e.g water , brine solution e.t.c)
d
In order to solve this problem here are the following ways
- When selecting steel the ones with a carbon percentage 0.3% to 0.8% should be selected
- When quenching the quenching medium should be brine solution
Explanation:
The reason why the answer to question is hardness test is because the heat treatment was carried out to obtain hardness so if it is great then the heat treatment is good
It depends on the type of weather and on the type of construction but I would say False
Let me know if it’s correct
Have a great day :)
