Ответ: 1,6 кН.

Answer 2

Calculating the Force on the Nail

To calculate the force acting on the nail when using the pliers to cut it, we can use the principle of moments. The force applied by the hand on the pliers will be transmitted to the nail. The distance from the axis of the pliers to the nail and the distance from the axis to the point where the hand applies the force are given.

Given: - Distance from the axis of the pliers to the nail, r1 = 2 cm - Distance from the axis of the pliers to the point where the hand applies the force, r2 = 16 cm - Force applied by the hand on the pliers, F = 200 N

Using the principle of moments, the force on the nail can be calculated using the formula:

F1 = (r2 / r1) * F

Substituting the given values: F1 = (16 cm / 2 cm) * 200 N

Calculating: F1 = 8 * 200 N F1 = 1600 N

Answer

The force acting on the nail is 1600 N.
