A bridge foundation has a nominal load capacity of 1700kN. If the resistance factor for this foundation is 0.65, what is the ult
Alekssandra [29.7K]

Answer:

The appropriate answer will be "2353.8 K". A further solution is given below.

Explanation:

The given values are:

Ultimate capacity,

= 1700kN

Resistance factor,

F.S = 0.65

According to the the LRFD, the allowable bearing pressure will be:

⇒ Pallo w = \phi_c\times \frac{Pn}{F.S}

On substituting the values, we get

⇒             =0.9\times \frac{1700}{0.65}

⇒             =2353.8 \ K

According to the the ASD, the allowable bearing pressure will be:

⇒ Pallow=\frac{Pn}{\Omega \times F.S}

On substituting the values, we get

⇒             =\frac{1700}{1.67\times 0.65}

⇒             = \frac{1700}{1.0855}

⇒             =1845.35 \ K

What is the derivative of?
Wewaii [24]

Answer:

cot(x)

Explanation:

\frac{d}{dx}ln(sin(x))

Use u-substitution,

u=sin(x)\\u'=cos(x)

\frac{d}{dx}ln(sin(x)) = \frac{d}{du}ln(u)

= \frac{1}{u}u'     //using the chain rule

= \frac{1}{sin(x)}cos(x)

=cot(x)

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.
