F = 3 Newton – the force that acts on the lever;
dx = 15 centimeters is the shoulder length of this force.
It is required to determine p (N * m) – the moment of force F.
We translate the units of measurement of length into the SI system:
dx = 15 cm = 15 * 10 ^ -2 = 15/100 = 0.15 meters.
Then, to determine the moment of force, you must use the following formula:
p = F * dx = 3 * 0.15 = 0.45 N * m (Newton per meter).
Answer: the moment of force F is equal to 0.45 N * m.
One of the components of a person's success in our time is receiving modern high-quality education, mastering the knowledge, skills and abilities necessary for life in society. A person today needs to study almost all his life, mastering everything new and new, acquiring the necessary professional qualities.
