23.8° The wheel rolls with no slip. Rod AO drives the wheel such that the velocity of the rod (and the center of the wheel) is v=1.5 m/s to the right, increasing at a rate of a=1 m/s². At this instant, 0-30°. Find the angular acceleration of the slotted link and the acceleration of P relative to the slot. Geometry is shown below. (Partial Answer: a=672 rad/s² CW, *xy = 56 downward along the slot) 113.4 mm, ww 9.98 C 123.9 mm 30% P 100 mm A 100 mm 200 mm.
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).
