Lecture



5.11. The work of external forces during the rotation of a solid body

Consider the action of an external force. 5.11. The work of external forces during the rotation of a solid body applied to a mass point 5.11. The work of external forces during the rotation of a solid body . During 5.11. The work of external forces during the rotation of a solid body elementary mass 5.11. The work of external forces during the rotation of a solid body goes way 5.11. The work of external forces during the rotation of a solid body Work force 5.11. The work of external forces during the rotation of a solid body on this path is determined by the projection of the force on the direction of movement, which is obviously equal to the tangential component 5.11. The work of external forces during the rotation of a solid body strength

5.11. The work of external forces during the rotation of a solid body

But 5.11. The work of external forces during the rotation of a solid body equal to the modulus of the moment 5.11. The work of external forces during the rotation of a solid body strength 5.11. The work of external forces during the rotation of a solid body relative to the axis of rotation. Job 5.11. The work of external forces during the rotation of a solid body and will be positive if 5.11. The work of external forces during the rotation of a solid body has the same direction as 5.11. The work of external forces during the rotation of a solid body   negative if the direction of the vectors 5.11. The work of external forces during the rotation of a solid body and 5.11. The work of external forces during the rotation of a solid body   opposite.

Given that 5.11. The work of external forces during the rotation of a solid body

5.11. The work of external forces during the rotation of a solid body

The work of all forces applied to the body

5.11. The work of external forces during the rotation of a solid body (5.13)
