Rotational Motion Iit Jee Pdf Rotation Around A Fixed Axis By “fixed axis” we mean that the axis must be fixed relative to the body and fixed in direction relative to an inertia frame. the discussion of general rotation, in which both the position and the direction of the axis change, is quite complex. 2 11.1 rotational kinematics (i) θ=s r form the definition of a radian (arc length radius) we know. We shall analyze the motion of systems of particles and rigid bodies that are undergoing translational and rotational motion about a fixed direction. because the body is translating, the axis of rotation is no longer fixed in space. we shall describe the motion by a translation of the center of mass and a rotation about the center of mass.
Chapter 1 Rotational Motion Pdf Rotation Around A Fixed Axis Likewise, for fixed axis rotation, has a sign, depending on the sense of rotation. more generally, when the axis is not fixed, we define the vector angular velocity with direction = the direction of the axis "right hand rule". curl fingers of right hand around rotation, thumb points in direction of vector. v : ( ) (–) ( ) (–) s. Figure 10.7.3: a disk is free to rotate about its axis through the center. the magnitude of the torque on the disk is rfsin θ.when θ = 0°, the torque is zero and the disk does not rotate. when θ = 90°, the torque is maximum and the disk rotates with maximum angular acceleration. V. t. e. rotation around a fixed axis or axial rotation is a special case of rotational motion around an axis of rotation fixed, stationary, or static in three dimensional space. this type of motion excludes the possibility of the instantaneous axis of rotation changing its orientation and cannot describe such phenomena as wobbling or precession. Torque is either clockwise or counterclockwise relative to the chosen pivot point. figure 10.31 shows counterclockwise rotations. figure 10.31 torque is the turning or twisting effectiveness of a force, illustrated here for door rotation on its hinges (as viewed from overhead). torque has both magnitude and direction.

The total work done to rotate a rigid body through an angle θ about a fixed axis is the sum of the torques integrated over the angular displacement. the work energy theorem relates the rotational work done to the change in rotational kinetic energy: w ab = k b − k a. the power delivered to a system that is rotating about a fixed axis is the.
