Fizika 10 Miakishev — Konspekt Uroka Po Teme Statika

The point through which the resultant of all gravitational forces acting on the particles of the body passes, regardless of the body's orientation. For simple geometric shapes made of uniform material, it coincides with the geometric center.

): The shortest distance (perpendicular) from the axis of rotation to the line of action of the force. The product of the magnitude of the force ( ) and its lever arm ( M=F⋅dcap M equals cap F center dot d Units: Newton-meters (N·m). fizika 10 miakishev konspekt uroka po teme statika

To ensure a body does not move translationally or rotate, two conditions must be met simultaneously: The point through which the resultant of all

The algebraic sum of the moments of all external forces about any axis of rotation must be zero. ∑Mi=0sum of cap M sub i equals 0 The product of the magnitude of the force

The vector sum of all external forces acting on the body must be zero.

∑F⃗i=0sum of modified cap F with right arrow above sub i equals 0
