Answer:
Step-by-step explanation:
Given:
elongation, x = 0.50 in
Force, f = 9000 lb
Young modulus, E = 10,000,000 psi
Maximum Stress, Sm = 30000 psi
Length, L = 16 ft
Converting ft to in,
12 in = 1 ft
=16 × 12 = 192 in
Young modulus, E = stress/strain
Stress = force/area, A
Strain = elongation, x/Length, L
E = f × L/A × E
1 × 10^7 = stress/(0.5/16)
= 26041.7 psi
Minimum stress = 26041.7 psi
Maximum stress = 30,000 psi
Stress = force/area
Area = 9000/26041.7
= 0.3456 in^2
Stress = force/area
Area = 9000/30000
= 0.3 in^2
Using minimum area of 0.3 in^2,
A = (pi/4)(d^2)
0.3 in^2 = (pi/4)(d^2)
d = 0.618 inches
diameter, d = 0.618 inches
Answer:
174 feet below sea level
Step-by-step explanation:
y is the number of minutes so you can multiply 14 by 9
14*9 is 126
then you add 126 to -300
126 + (-300) is essentially 126 - 300 and that is -174
the submarine was at 174 feet below sea level
Answer:
D) 72 is correct because 8 times 9 is 72! Hope this helped. :)
Answer to 21 5 stands for left handers and 8 for right handers. Their are 45 left handers. 45/5 is 9. 9 times 8 is 72. for section b 5+8 is 13 so the answer is 5 over 13. Answer to 24 the table goes 1:5:7, 2:10:14,3:15:21, 4:20:28 on 7 graders the open spaces are 14 and 21 so their is 7 seventh graders for each moral. Their are 5 6th graders because on the first space their are 5 and it is one moral.
