6. Calculate the moment of inertia of a baseball bat about the handle (in kgm) given...
6. A baseball bat has a mass of 0.85 kg. If the player holds that bat near the handle, the distance from the hands (axis of rotation) to the center of mass of the bat is 0.75 m. What is the moment of inertia for the bat? If the player chokes up 5 cm (0.05 m), what would be the new moment of inertia for the bat (subtract this 0.05 m from the 0.75 m).
The dogs model a baseball bat as a rod of increasing linear mass density that goes as: λ = 1.2x moment of inertia if the bat is length L and it is swung about the low density end? (b) What is the moment of inertia if it is swung about an axis that is 0.1L away from the low density end? 2. . (a) what is the The dogs model a baseball bat as a rod of increasing linear mass...
If a wheel of the moment of inertia 24 kgm moves at a velocity of 6 m/s and has an angular momentum of 36 kgm/s, what is its radius? 2 m 4 m 6 m 3 m
if the whole leg has a moment of inertia of 5.10 kgm^2 about the COM and a mass of 10.5 kg determine the moment of inertia about the hip which is 0.45 metres away from the COM.
1. The moment of inertia (sometimes referred to as a “swing weight”) is a measure of the resistance to rotation about a particular axis. It is often expressed as Ia = mka2 where m is the mass of the object and ka is the radius of gyration about the axis of rotation. The radius of gyration ka for the arm about its COM = 0.368*(arm length). Compute the moment of inertia of the arm in the extended position about its...
The forearm of a person has a moment of inertia of 0.08 kgm^2 about the elbow joint. the forearm is held vertically and the bicep muscles exerts a horizontal force on the forearm at a perpendicular distance of 2.1 cm from the elbow's rotation axis. if the forearm has the resulting angular acceleration of 1.2 rad/s^2, what is the magnitude of the biceps muscle's force?
6. (a) Calculate the moment of inertia about the center of mass. (b) Calculate h, the moment of inertia about an axis through point B. Point B coincides with (the center of) one of the spheres (see the figure). (c) Calculate Ic, the moment of inertia about an axis through point C. Point C is located a distance r from the center of mass (see the figure). (d) Calculate kinetic energy when it rotates about an axis through C with...
Calculate the moment of inertia of the following figure about the axis O. A is a uniform solid cylinder with mass M and radius R. B is a uniform thin rod with mass M and length 3R. A and B objects are attached together and rotate together about axis O. The distance X is and Y is in the figure. The light blue line is going through the center of the cylinder and the point “CM” represents the center of mass of...

Figure 1:Part A: A baseball bat can be rotated around many different axes of rotation. Three such possibilities are shown in (Figure 1) . Rank the baseball bat's moment of inertia about each of these three axes of rotation.Rank the moment of inertia from largest to smallest and overlap axes labels if the same.Part B: Given the same baseball bat and possible axes of rotation shown in (Figure 1) , for which axis of rotation would it be the easiest...
