A force of magnitude F making an angle with the x axis is applied to a particle located along axis of rotation A, at Cartesian coordinates (0, 0) in the figure. The vector Flies in the xy plane, and the four axes of rotation A, B, C, and D all lie perpendicular to the xy plane. (Figure 1) Figure B To C 1 of 1 A particle is located at a vector position with respect to an axis of rotation (thus 7 points from the axis to the point at which the particle is located). The magnitude of the torque 7 about this axis due to a force Facting on the particle is given by TrF sin(a) = (moment arm). F = TF₁, where a is the angle between 7 and F, r is the magnitude of F, F is the magnitude of F, the component of that is perpendicular to F is the moment arm, and F₁ is the component of the force that is perpendicular to 7. Sign convention: You will need to determine the sign by analyzing the direction of the rotation that the torque would tend to produce. Recall that negative torque about an axis corresponds to clockwise rotation. In this problem, you must express the angle a in the above equation in terms of 0, 0, and/or when entering your answers. Keep in mind that π = 180 degrees and (π/2) = 90 degrees. ▼ Part A What is the torque Tabout axis A due to the force F? Express the torque about axis A at Cartesian coordinates (0,0).

Express the torque about axis B in terms of F, 0, 0, π, and/or other given coordinate data. from the origin along the
Rigid Body
A rigid body is an object which does not change its shape or undergo any significant deformation due to an external force or movement. Mathematically speaking, the distance between any two points inside the body doesn't change in any situation.
Rigid Body Dynamics
Rigid bodies are defined as inelastic shapes with negligible deformation, giving them an unchanging center of mass. It is also generally assumed that the mass of a rigid body is uniformly distributed. This property of rigid bodies comes in handy when we deal with concepts like momentum, angular momentum, force and torque. The study of these properties – viz., force, torque, momentum, and angular momentum – of a rigid body, is collectively known as rigid body dynamics (RBD).
