In physics, a rigid body is an object that is not deformed by the stress of external forces. The term "rigid body" is used in the context of classical mechanics, where it refers to a body that has no degrees of freedom and is completely described by its position and the forces applied to it. A rigid body is a special case of a solid body, and is one type of spatial body. The term "rigid body" is also used in the context of continuum mechanics, where it refers to a solid body that is deformed by external forces, but does not change in volume. In continuum mechanics, a rigid body is a continuous body that has no internal degrees of freedom. The term "rigid body" is also used in the context of quantum mechanics, where it refers to a body that cannot be squeezed into a smaller volume without changing its shape.

In physics, rotational dynamics is the study of the kinematics and kinetics of rotational motion, the motion of rigid bodies, and the about axes of the body. It can be divided into the study of torque and the study of angular velocity.

So this problem is very similar to a mass on inkling and raising this until this object begins to slide. So we could drop three bloody dagger, my normal force like gravity and my friction, which is act intentions to the support 10 digits lotion again very similar to an object at a slightly down See that everybody died. So our component of gravity here at its maximum will be equal to my friction when it begins to look so my friction will be equal. Two mg signed data at its maximum value. So mg science data use perfection. And we know that my maximum static friction is my co positions static friction from my normal force which in this case, my normal force is equal to empty coastline, Which is that components. Obviously that haunted my normal course, which is into a four descended circle here. So these MGs counsel and I'm left with signe data over Holstein Vega. People's new s now scientists over co signed it is Sam just Vita, and then we can solve for the ankle by getting the inverse of the coefficients of Saturday. So get the engines in verse of point seven. That's getting in the problem. An ankle of 34.99 or 35 theories
