What steel type and ASTM designation is preferred for W-shapes?

Ulleksa [173]

Answer:

The preferred steel type for W-shapes is structural steel and the its preferred ASTM designation is ASTM A992.

Explanation:

The ASTM A992 is a structural steel and it's the most available for w-shapes; besides its availabilty, its ductility improvements makes it the preferred choice; other common designations for this shapes are ASTM A572 Grade 50,0r ASTM A36, but this designations aren't as available as ASTM A992, and it has to be confirmed prior to their specification.

Computers work with only two states: zero and one (e.g. short , tall)and is known as binary however in fuzzy logic there are ran

Ymorist [56]

Answer:

1) a)True

b) False

2) False

2. True

4. True

5. True

Explanation:

1.a)Computers work with only two states: zero and one which is true, the language is in 1 and 0 which is called binary

b)in fuzzy logic there are range of states such as short, little tall, very tall etc...

That is false because Fuzzy logic contains also ones and zeros (Binary).

2)2. This is false because by combining the three colors we will get only

256*256*256 color and we don't get billions of colors

eg:R G B

255 0 0 -->one color

220 0 200---> one color

Due to the difficult economic times, increased global competition, demand for customization, and increased consumer sophistication, many companies have increased their investment in hiring many employees, and outsource & off shore middle managers True or False

yes this may be True because By increased global competition, demand for customization the product needs to be developed. And for development of new products we need employees, managers etc. This in-turn increases the outsourcing of offshore middle managers.

A mouse driver (software) can have a virus if its program gets infected true or False

This is True

It depends on the virus file. Some program need to be execute perfectly if it can be infected with virus. Some applications need not run because of virus files both the situations are possible.

5)Many managers were able to tackle y2k on time and saved billions. true or False;

This is True. After the year 2000, a lot of managers are able to control billions of people because many of the Top MNC's are tackled more by managers.

the hoop is cast on the rough surface such that it has an angular velocity w=4rad/s and an angular acceleration a=5rad/s^2. also

IgorLugansk [536]

Given Information:

Angular velocity = ω = 4 rad/s

Angular acceleration = α = 5 rad/s²

Center deceleration = a₀ = 2 m/s

Required Information:

Acceleration of point A at this instant = ?

Answer:

Acceleration of point A at this instant = 5.94 m/s²

Explanation:

Refer to the attached diagram of the question,

The acceleration of point A is given by

a = a₀ + rα - rω²

Where r is the radial distance between the center and point A, a₀ is the deceleration of center, α is the angular acceleration and ω is the angular velocity.

a = -2i + 0.3j*5k - 0.3j*4²

a = -2i + 1.5(j*k) - 0.3j*16

a = -2i + 1.5(-i) - 4.8j

a = -2i - 1.5i - 4.8j

a = -3.5i - 4.8j

The magnitude of acceleration vector is

a = √(-3.5)² + (-4.8)²

a = √35.29

a = 5.94 m/s²

Therefore, the acceleration of point A is 5.94 m/s²

The angle is given by

θ = tan⁻¹(y/x)

θ = tan⁻¹(-4.8/-3.5)

θ = 53.9°

What type of bond guarantees that if a contractor goes bankrupt on a project the surety will pay the necessary amount to complet

Morgarella [4.7K]

Answer: Payment bond.

Explanation:

A payment bond is a type of guaranteed payment provided for a contractor which ensure that all subcontractors, suppliers, workers etc involved in a project will be duly paid. Payment bond usually comes along with performance bond especially in the construction industry, and it is obtained before the commencement of a construction project. This serves as a form of protection for subcontractors.
