Given the following: Length of rod = 10 inches Angle alpha = 30 degrees Determine the magnitude of the y component of the resultant moment (My) of the rod, given the applied force, around point B. Write the numerical value without the unit. Put - sign to the numerical value (e.g. -0.9) if the rotation is clockwise. If the rotation is counter clockwise, do not put negative sign (e.g. 0.9). Solve up to 4 decimal places. Fa 65° 20 lb B
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).
