To study torque experimentally, you apply a force to a beam. One end of the beam is attached to a pivot that allows the beam to rotate freely. The pivot is taken as the origin or your coordinate system. You apply a force of F = Fx i + Fy j + Fz k at a point r = rx i + ry j + rz k on the beam.
A. Calculate the magnitude of the torque, in newton meters, when the components of the position and force vectors have the values 1.-2.59 m. ry = 0.075 m. r=0.095 m, F, = 4.6 N, Fy=-4.8 N, F,= 1.2 N. 33%
B. If the moment of inertia of the beam with respect to the pivot is / 272 kg'm', calculate the magnitude of the angular acceleration of the beam about the pivot, in radians per second squared.
