4. Consider a circular object that is free to rotate about its central axis. The object is sitting horizontally on ice, so that ction is negligible. (Think of a hockey rotating, or more precisely to change its rate of rotation? Is it a net force, which is the cause of changes in linear motion, or is it something else? puck.)

As shown in the figure below, we have a square one meter on a side that is free to rotate about an axis perpendicular to the plane of the square, a distance a from one side and a distance b from the other side.Two forces, F1 and F2 are applied to diagonally opposite corners, and act along the sides of the square, first as shown in case (t) and then as shown in case (ii) of the drawing. In each...

The wide A 2 kg solid cylinder can rotate about its central axis through point O. Forces are applied as shown: F1 = 6 N, F2 = 4 N, F3 = 10 N and FA = 20 N. The positions at which the forces are applied are Ri = 6 cm and R2 = 12 cm. During the rotation, all forces maintain their same angles relative to the cylinder. Find the angular acceleration (magnitude and direction) of the cylinder. Rotation...

Q-4 (25 pts A uniform bar of length (L), cross sectional area (A) and mass (m) is free to rotate about a frictionless hinge at "O" in a horizontal plane. At the instant shown its angular velocity is (w) rad/sec clockwise and the applied torque (T) is clockwise. For the instant determine: a) The reactions at the hinge "O b) The internal forces (Shear force V, axial force F) in the middle of the bar (xeL/2 from hinge "O") Hint:...

INVESTIGATION 10 ROTATIONAL MOTION OBJECTIVE To determine the moment of inertia I of a heavy composite disk by plotting measured values of torque versus angular acceleration. THEORY Newton's second law states that for translational motion (motion in a straight line) an unbalanced force on an object results in an acceleration which is proportional to the mass of the object. This means that the heavier...

Consider a cylindrical capacitor like that shown in Fig. 24.6. Let d = rb − ra be the spacing between the inner and outer conductors. (a) Let the radii of the two conductors be only slightly different, so that d << ra. Show that the result derived in Example 24.4 (Section 24.1) for the capacitance of a cylindrical capacitor then reduces to Eq. (24.2), the equation for the capacitance of a parallel-plate capacitor, with A being the surface area of...
