Answer:
a) k
= 3.6 N/m ; b) 9.43 * 10¹²; c) 1.18 * 10¹¹; d) 75.08 N/m
Step-by-step explanation:
Length of iron bar = L = 2.7m;
side length of cross section = a = 0.07cm = 0.0007m;
x = 2.7 cm = 0.027m;
m = 100kg;
ρ = 7.87gm/cm³;
da = 2.28 * 10⁻¹⁰m;
a)
Fnet = F - mg
where Fnet = 0
So,
F = mg where F=kx
k = mg/x = 100*9.8/0.027
k = 3.6 N/m
b)
Nchain = Aw/Aa =a²/(da)²
= (o.ooo7)²/(2.28 * 10⁻¹⁰)²
= 9.43 * 10¹²
c)
Nbond = L/da = 2.7/2.28 * 10⁻¹⁰
= 1.18 * 10¹¹
d)
Spring stiffness of wire = ksi = (Nbondk)/Nchain
= [(1.18* 10¹¹)(6*10⁴)]/(9.43 * 10¹²)
= 75.08 N/m
Answer:
x = - 6
Step-by-step explanation:
Given
4(x + 6) - 2x = 12 ← distribute and simplify left side
4x + 24 - 2x = 12
2x + 24 = 12 ( subtract 24 from both sides )
2x = - 12 ( divide both sides by 2 )
x = - 6
Hello!
1 cubic centimeter = 0.001 liter
105 cubic centimeters = 0.001 × 105
0.001 × 105 = 0.105
Answer ⇒ 0.105 L
Hope this helps! :)
