Answer:
Titanium Alloy
Explanation:
Length ( L ) = 20 mm
D1 = 20 mm
d2 = 18 mm
l = 20 mm
Mechanical efficiency = 50%
power = 80 kW
cutting rake angle = 0°
cutting speed ( v ) = 10 m/s
<u>Determine the material to be for the cylinder </u>
In order to choose a material for the cylinder we have to calculate the cutting force
P = Fc * V
80 = Fc * 10 m/s
therefore Fc = 80 / 10 = 8 N
Hence the material we can use is Titanium Alloy due to low cutting force value
Answer:
Between 5 & 10 MPa in Table B.1.4
Explanation:
150F = 65°C
State 1:
T = 65°C , x = 0.0; Table B.1.1: v = 0,001020 m^3
/kg
Process: T = constant = 65°C
State 2:
T, v = 0.99 x v
f (65°C) = 0.99 x 0,001020 = 0.0010098 m^3
/kg
Between 5 & 10 MPa in Table B.1.4
Explanation:
The wind is an actual form of solar energy. winds are caused by the heating of the atmosphere by the sun, the rotation of the earth, and the earth's surface irregularities. The wind is capture in a wind turbine which provides a renewable energy source, the wind makes the rotor spin, as the rotor spins the movement of the blades drives a generator that creates energy, also known as wind power. The average wind efficiency of turbines is between 35-45%.
Advantages of wind power
- Wind power is cost-effective
- wind creates jobs
- wind enables US industry growth and US competitiveness
-it's a clean fuel source
