Answer:
we might say the earth rotates at 7.272×10-5 rad/s and this tells us in its angular speed
Answer:
a) 0.2099
b) 46.5 MPa
c) 233765 N
d) 3896 W
Explanation:
a)
r = (A'' - A') / A'', where
A'' = 1/4 * π * D''²
A'' = 1/4 * 3.142 * 90²
A'' = 6362.55 mm²
D' = D'' - d = 90 - 10 = 80 mm
A' = 1/4 * π * D'²
A' = 1/4 * 3.142 * 80²
A' = 5027.2 mm²
r = (A'' - A') / A'
r = (6362.55 - 5027.2) / 6362.55
r = 1335 / 6362.55
r = 0.2099
b)
Draw stress = σd
Y' = k = 105 MPa
Φ = 0.88 + 0.12(D/Lc), where
D = 0.5 (90 + 80) = 85 mm
Lc = 0.5 [(90 - 80)/sin 18] = 16.18 mm
Φ = 0.88 + 0.12(85/16.18) = 1.51
σd = Y' * (1 + μ/tan α) * Φ * In(A''/A')
σd = 105 * (1 + 0.08/tan18) * 1.51 * In(6362.55/5027.2)
σd = 105 * 1.246 * 1.51 * 0.2355
σd = 46.5 MPa
c)
F = A' * σd
F = 5027.2 * 46.5
F = 233764.8 N
d)
P = 233764.8 (1 m/min)
P = 233764.8 Nm/min
P = 3896.08 Nm/s
P = 3896.08 W
Answer: Determine the number of pumps in each of the two six-pump gas stations.
• X = the total No. of pumps that are in use at the 2 stations
• Y = the difference between the No. of pumps in utilization at station 1 and the
NO. of pumps in use at the station 2
• U = the max number of pumps in use at the 2 stations
W (observed) = (3, 4)
X (W) = 3 + 4 = 7
Y (W) = 3 − 4 = − 1
U (W) = max (3, 4) = 4
As a free and open operating system, Android allows app developers to generate new ideas and work with a wide range of smartphones to open up hardware options, as companies supply a great variety of devices to choose from and high-end devices become more affordable.25 Jan 2017
Answer:
This might reduce outage probability because multiple base stations are able to receive a given mobile signal at a time which lead to signal outage decrease or weakness.
