A cylinder has a cone removed from it. The cylinder and the conical hole have the same radius (2.06 meters) and height (4.56 meters). The cylinder has a density of 447 kg/m3.
What is the rotational inertia of the cylinder with the cone removed in kg m2? You can set your origin at the tip of the cone, which is also the center of the base of the cylinder.
going to calculate the theoretical value of the moment of inertia of the rotor, using the measurements given below. The rotor consists of 4 cylindrical segments which are fused together. The moment of inertia of a solid cylinder is I = (1/2)MR^2. To calculate I for the rotor, add the individual I values of the 4 cylindrical segments. This means that you will have to calculate the mass of each segment. Assume that the density of the rotor (M/V) is uniform. Recall that the volume of a cylinder is given by V = πR^2L.
A 200 g uniform rod of length 5.0 m is pivoted about one end. What would be the angular acceleration due to gravity if the rod were held horizontally and released from rest?
