I have an assignment that asks to find a torque from given angular velocity, mass and moment of inertia. For a turntable disk, mass is known as 0.04452199 kilograms The Angular velocity should be 106.81 (rads/sec) These values are from solidwork file (anyone familiar with Solidworks?) Center of mass: ( meters ) X = -0.01474448 Y = -0.00659061 Z = 0.04376940 Principal axes of inertia and principal moments of inertia: ( kilograms * square meters ) Taken at the center of mass. Ix = (-0.70029829, 0.71385033, 0.00002079) Px = 0.00001872 Iy = (-0.71385033, -0.70029829, -0.00002111) Py = 0.00001875 Iz = (0.00000000, -0.00002962, 1.00000000) Pz = 0.00003073 Moments of inertia: ( kilograms * square meters ) Taken at the center of mass and aligned with the output coordinate system. Lxx = 0.00001874 Lxy = -0.00000001 Lxz = 0.00000000 Lyx = -0.00000001 Lyy = 0.00001874 Lyz = 0.00000000 Lzx = 0.00000000 Lzy = 0.00000000 Lzz = 0.00003073 Moments of inertia: ( kilograms * square meters ) Taken at the output coordinate system. Ixx = 0.00010596 Ixy = 0.00000431 Ixz = -0.00002873 Iyx = 0.00000431 Iyy = 0.00011371 Iyz = -0.00001284 Izx = -0.00002873 Izy = -0.00001284 Izz = 0.00004234 As far as I know, equation for torque is angular acceleration X moment of inertia, but in this case, I don't have Angular acceleration but velocity. and Radius is unknown. Is it possible to get a value of Torque from these information? I am keep looking for way to approach this question but I am having a hard time with it. Any help will be appreciated.
