Answer:
the application of scientific knowledge for practical purposes, especially in industry.
2. machinery and equipment developed from the application of scientific knowledge.
3. the branch of knowledge dealing with engineering or applied sciences.
Explanation:
I think it's false because the theory states that electrons flow from negative to positive. Since electrons are negatively charged, it follows that they are attracted by positively charged bodies and repelled by negatively charged bodies.
Answer:
C) CNC system.................
Answer:
(1) , (2) , (4) ,(6).
Explanation:
Use of casting process:
1.When the size of the mold is more or we can say that when the size of casting is more.
2.When the mechanical strength of the casting product is not important.
3.When the required ductility of the product is not to high .Generally casting product is more brittle with high strength.
4.Generally cost of casting product is not too high or we can say that casting product is economically.
Therefore the following options are correct -
(1) , (2) , (4) ,(6).
Answer:
The PT station is at 485+20.02 and 21.92 ft are to be cleared from the lane's shoulder to provide adequate stopping sight distance.
Explanation:
From table 3.5 of Traffic Engineering by Mannering
R_v=835
R=835+(10ft/2)= 840 ft.
Now T is given as
T=R tan(Δ/2)
Here Δ is the central angle of curve given as 35°
So
T=R tan(Δ/2)
T=840 x tan(35/2)
T=840 x tan(17.5)
T=264.85
Now
STA PC=482+72-(2+64.85)=480+07.15
Also L is given as
L=(π/180)RΔ
Here R is the radius calculated as 840 ft, Δ is the angle given as 35°.
L=(π/180)RΔ
L=(π/180)x840 x35
L=512.87 ft
STA PT=480+07.15+5+12.87=485+20.02
Now Ms is the minimum distance which is given as

Here R_v is given as 835
SSD for 50 mi/hr is given as 425 ft from table 3.1 of Traffic Engineering by Mannering
So Ms is

Now for the clearance from the inside lane
Ms=Ms-lane length
Ms=26.92-5= 21.92 ft.
So the PT station is at 485+20.02 and 21.92 ft are to be cleared from the lane's shoulder to provide adequate stopping sight distance.
