Question

Using the Equilibrium Equation (F1d1 = F2d2), find F1, if d1 = 30ft, and F2 = 1050lb, and d2=22ft. Please state your answer in pounds and round to the nearest whole number.

Answer 1

Answer:

77 lb

Explanation:

Equation: F₁d₁ = F₂d₂

Knowns:

d₁ = 30 ft

F₂ = 105 lb

d₂ = 22 ft

Solving for F₁:

1). F₁•30 = 105•22

2). F₁•30=2,310

3).$\frac{F_1\cdot 30}{30}=\frac{2310}{30}$

4). F₁ = 77 lb
