Which of the following manufacturing tools machines parts by moving the part into the cutting tool (instead of moving the cutting tool into the part).A.) Lathe
B.) Drill Press
C.) Injection Molder
D.) Milling Machine

Answers

Answer 1

Answer:

Lathe is the manufacturing tools machines parts by moving the part into the cutting tool.

Explanation:

The metals, other materials or wood are shaped as pieces using the machine tool which is lathe.
Lathe is identified as three kinds: Engine lathe, Special purpose lathe, Turret lathe.
Semi-portable and bench mounted are smaller ones.
Floor mounted are large lathe it needs special transportations to move.
Engine lathe can be moved from one area to another because its not too large. The lathe which is adapted many operations are used in maitanance shop.
Special purpose lathe and Turret lathe is used in mass production.

Only option a and the option b follows the first law of thermodynamics.

Explanation:

As we know that the first law of thermodynamics tells the conservation of energy, that is why it is also called quantitative law.

From the first law of thermodynamics

$Q=\Delta E+W$

a. Given that

W= 50 KJ,Q = 170KJ ,ΔE = 120 KJ

Yes, this follows the first law of thermodynamics.

b. Given that

W= 100 Btu,Q= -110 Btu ,ΔE= -210 Btu

This also satisfy the first law of thermodynamics.

c. Given that

W= 250 KJ,Q= -110 KJ ,ΔE=-100 KJ

Yes this does not follow the first law of thermodynamics.

d. Given that

Yes, this does not follow the first law of thermodynamics.

Compared to 15 mph on a dry road, about how much longer will it take foryou to stop at 30 mph on a snow-covered road?

2 to 3 times

4 to 6 times

8 to 10 times

Answers

Answer:

8 to 10 times

Explanation:

For dry road

u= 15 mph ( 1 mph = 0.44 m/s)

u= 6.7 m/s

Let take coefficient of friction( μ) of dry road is 0.7

So the de acceleration a = μ g

a= 0.7 x 10 m/s ² ( g=10 m/s ²)

a= 7 m/s ²

We know that

v= u - a t

Final speed ,v=0

0 = 6.7 - 7 x t

t= 0.95 s

For snow road

μ = 0.4

de acceleration a = μ g

a = 0.4 x 10 = 4 m/s ²

u= 30 mph= 13.41 m/s

v= u - a t

Final speed ,v=0

0 = 30 - 4 x t'

t'=7.5 s

t'=7.8 t

We can say that it will take 8 to 10 times more time as compare to dry road for stopping the vehicle.

8 to 10 times

I would say 2-3 times but I’m not quite sure

What lights should be used in a sailboat at night?

A sailboat is operating under sail at night is known to be one where the operator of that sailboat is said to be operating under sails at darkness and so their sidelights should be (red - green) and stern light (white).

When they are said to be less than 20 meters in length, the three lights can be use altogether at or near the top of the mast.

Answer:

White Stern light

Explanation:

According to boating regulations, navigation lights must be used for safety purposes when operating water vessels especially during the night.

The boating regulations for operating sailboats, specify that a white stern light must be used during hours from sunset to sun rise. This is to indicate the presence of the sea craft on the ocean, as well as its direction.

A stern light is a white light placed as closely as practical at the stern shining constantly. It covers an angle of 135 degrees, and helps show the direction of the boat.
