Fixed pulley. But it has to make multiple strands so you can get a higher mechanical advantage
<span>Since the force is applied at an angle from the
horizontal, we will use the horizontal component of this force in calculating
for the displacements.
From derivation, the Fx is:</span>
Fx = F cos φ
Where:
Fx = is the horizontal component of the force
F = total force
φ =
angle in radian = 37 * pi / 180 = 0.645 rad
Calculating: Fx = 30.0 N * cos(0.645)
Fx = 23.97 N = 24 N
Calculating for Work: W = Fx * d
A. W = 24 N * 15 m = 360 N
B. W = 24 N * 16 m = 384 N
C. W = 24 N * 12 m = 288 N
D. W = 24 N * 14 m = 336 N
Explanation:
To balance this equation, let us properly write it;
C₇ H ₁₆ + O₂ → CO₂ + H₂O
Every chemical equation obeys the law of conservation of matter in which the number of species on both sides must be equal.
To solve this problem, rather than inspection, we use some simple, solvable algebraic equations:
aC₇ H ₁₆ + bO₂ → cCO₂ + dH₂O
a, b, c and d are the coefficients that will balance the equation;
conserving C : 7a = c
H: 16a = 2d
O: 2b = 2c + d
let a = 1
c = 7
d = 8
b = 11
C₇ H ₁₆ + 11O₂ → 7CO₂ + 8H₂O
