WebAnswer (1 of 6): A moment of inertia is only a scalar quantity for a particular choice of axis about which to rotate the disk, not necessarily through its centre of mass. In general a moment of inertia is a tensor ,i.e. a matrix of values which are normally determined relative to the principal ax... WebAnswer: The torque can be found using the torque formula, and the moment of inertia of a solid disc. The torque is: τ = Iα τ = 0.0020 N∙m The torque applied to one wheel is 0.0020 N∙m. 2) The moment of inertia of a thin rod, spinning on an axis through its center, is , where M is the mass and L is the length of the rod. slow roast pork roast

Web2. I = I C M + M r 2, but in this case (using parallel axes theorem) I dont know how to calculate the I C M, since the mass distributtion is unkown (and not uniform because the center of mass is not in the center). 3. I = I C M + M r 2, where this time I C M is that of a uniform disk of mass M (so equals 1 2 M R 2 but this would be like saying ...

WebBecause the moment of inertia for a point mass is: I = m r 2 When calculating the moment of inertia for continuous bodies we use calculus to build them up from infinitesimal mass elements, so effectively to calculate the moment of inertia of the disk (without hole) we're doing: I d i s k = ∑ i d i s k m i r 2 WebMoment of Inertia. Moment of inertia is the name given to rotational inertia, the rotational analog of mass for linear motion. It appears in the relationships for the dynamics of rotational motion. The moment of inertia must be specified with respect to a chosen axis of rotation. For a point mass, the moment of inertia is just the mass times ...
