Question

Плечі важеля 2м і 3м. До другого плеча приклали силу 60Н. Яку силу необхідно прикласти до другого плеча, щоб важіль перебував у рівновазі?

Answer 1

Ответ:

Объяснение:

L1 = 2 м

L2 = 3 м

F2 = 60 H

F1 = ?

L1*F1 = L2*F2

F1 = L2*F2 / L1 = 3*60 / 2 = 90 H

Answer 2

Lever and Force Calculation

To calculate the force needed to maintain equilibrium on the lever, we can use the formula:

Force1 × Distance1 = Force2 × Distance2

Given: - Distance1 (first lever arm) = 2m - Distance2 (second lever arm) = 3m - Force1 = 60N (applied force at the first lever arm)

We need to find Force2.

Using the formula: Force1 × Distance1 = Force2 × Distance2

We can rearrange the formula to solve for Force2: Force2 = (Force1 × Distance1) / Distance2

Substitute the given values: Force2 = (60N × 2m) / 3m

Calculation

Let's calculate the force needed to maintain equilibrium on the lever:

Force2 = (60N × 2m) / 3m Force2 = 120N / 3m Force2 = 40N

So, the force needed to be applied to the second lever arm to maintain equilibrium is 40N.
