Answer:
Total wight =640.7927 KN
Explanation:
Given that
do= 61 cm
L =120
t= 0.9 cm
That is why inner diameter of the pipe
di= 61 - 2 x 0.9 cm
di=59.2 cm
Water density ,ρ = 1 kg/L = 1000 kg/m³
Weight of the pipe ,wt = 2500 N/m
wt = 2500 x 120 N = 300,000 N
The wight of the water
wt ' = ρ V g

wt'=340792.47 N
That is why total wight
Total wight = wt + wt'
Total wight =300,000+ 340792.47 N
Total wight =640,792.47 N
Total wight =640.7927 KN
Answer:
The strain is 0.0947.
Explanation:
Strain is the ration of change in dimension to the original dimension under application of load. Depending upon load, the bar may stretch or compress. So, the strain can be negative in case of compression or positive in case of tension.
Step1
Given:
Original length of the steel bar is 0.66 ft or 7.92 in.
Stretch in the bar is of 0.75 in.
Calculation:
Step2
Strain is calculated as follows:


e = 0.0947
Positive sign is for stretching condition of the bar.
Thus, the strain is 0.0947.
Answer: D. Many more people crossed the mountains and settled between the Appalachians and the Mississippi
Explanation:
It was quite difficult to cross the Appalachian mountains at the time of the American colonies which led to the colonies being confined to the east of it.
This was until the late 1700s when Daniel Boone and a team of explorers heard that a path existed through the Appalachians and had been used by natives for a long time. After discovering this ''gap'' which was then named after an English prince, many more people were able to use it to settle more to the west of the continent.
Answer:
displacement power factor is 0.959087
Explanation:
given data
THD = 88%
true power factor = 0.72
solution
we get here total harmonic distribution THD is express as here
THD =
..............1
her g is distortion factor
so put here value and we will get g that is
0.88² =
solve it we get
g = 0.750714
and
displacement power factor is express as
DPF =
.................2
put here value and we will get
DPF =
DPF = 0.959087
