Answer:
Step-by-step explanation:
Given:
Force, f = 9000 lb
Young modulus, E = 10,000,000 psi
Stress, S = 30000 psi
Elongation, x = 0.50 in
Length, L = 16 ft
Converting ft to in,
12 in = 1 ft
= 192 in
Young modulus, E = stress/strain
Stress = force/area, A
Strain = elongation, x/Length, L
Maximum stress = 30,000 psi
Stress = force/area
Area = 9000/30000
= 0.3 in^2
Using minimum area of 0.3 in^2,
A = (pi × d^2)/4
0.3 = (pi × d^2)/4
= sqrt(1.2/pi)
diameter, d = 0.62 inches
A percentage is a number out of 100. So, 17.5% is really 17.5/100, or 0.175.
To find 17.5% of 1500, you multiply 1500 by 0.175
1500 x 0.175 = 262.5.
The commission is $262.50.
