The detailed step by step derivation and appropriate integration is as shown in the attached files.
Answer:
The required rated input apparent power is 14.98 HP
Explanation:
Real power input = real power output ÷ efficiency
real power output = 12 HP
efficiency = 90% = 0.9
Real power input = 12 ÷ 0.9 = 13.33 HP
Apparent power input = real power input ÷ power factor = 13.33 ÷ 0.89 = 14.98 HP
Answer:
The correct option is B.
Explanation:
"An ideal randomized controlled experiment " best describes the statement mentioned in the question.
Answer:
0.39 nM
Explanation:
The critical crack tip radius from the equation
attached below
for fracture to occur the бm will have to reach the fracture strength of material
i.e. бm = E/10
from equation 2 attached below
St = ( 400 * a * бo^2 ) / E^2 ------ 3
Given <em>: a = 2*10^-3 mm , бo = 275 MPa, E = 393 * 10^3 MPa ( gotten from table)</em>
Input given values into equation 3
St = 3.9 * 10^-7 ≈ 0.39 nM
