Answer:
a) 280MPa
b) -100MPa
c) -0.35
d) 380 MPa
Explanation:
GIVEN DATA:
mean stress
stress amplitude
a)
--------------1
-----------2
solving 1 and 2 equation we get
b)
c)
stress ratio
d)magnitude of stress range
= 280 -(-100) = 380 MPa
Solution :
Given :
The power of the air‐conditioning (AC) unit is , W = 0.434 kW
The coefficient of performance or the COP of the air‐conditioning (AC) unit is given by = 6.22
Therefore he heat removed is given by ,
Now if the electricity is valued at 0.10 dollar per kW hour, then the operating cost of the air conditioning unit in 24 hours is given by = 0.10 x 2.7 x 24
= 6.48
Therefore the operating cost = $ 6.48 for 24 hours.

Answer:
The dependent variable is MEDV - Median value of owner-occupied homes in $1000's
Explanation:
The median value of the house has to be predicted, based on its properties and neighborhood properties, this can be done by using a linear regression model.
The dependent variable in Machine Learning is the output variable that we want to predict.
Therefore, according to the question given "MEDV" is the dependent variable.
Answer:
<em>hello your question is incomplete attached below is the missing diagram </em>
answer : 7.87 KN
Explanation:
The magnitude of the resultant force = 7.87 KN
from fig 1
First step :
calculate the resultant force along the x- direction
Frx = ∑Fx = +8 kN - Fcos45° - 14cos 30°
= -4.1243 - 0.7071 F
next :
calculate the resultant force along the y- direction
Fry = ∑Fy = -Fsin45° + 14sin30°
= -0.7071 F + 7
attached below is the remaining part of the detailed solution
