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).

As a torque activity, your Physics TA sets up the arrangement shown below. 3 fp = 8 F = 7₁ → A uniform rod of mass m, = 138 g and length L = 100.0 cm is attached to the wall with a pin as shown. Cords are attached to the rod at the r₁ = 10.0 cm and r₂ = 90.0 cm mark, passed over pulleys, and masses of m₁ = 266 g and m₂ = 157 g are attached. Your TA asks you to determine the following. (a) The position r3 on the rod where you would suspend a mass m3 = 200 g in order to balance the rod and keep it horizontal if released from a horizontal position. In addition, for this case, what force (magnitude and direction) does the pin exert the rod? Use standard angle notation to determine the direction of the force the pin exerts on the rod. Express the direction of the force the pin exerts on the rod as the angle 8, measured with respect to the positive x-axis (counterclockwise is positive and clockwise is negative). m4 Fp = 8 F = m N m₁ m₂ (b) Let's now remove the mass m3 and determine the new…
An ice figure skater is doing a spin with her hands on bar bells weighing 10 pounds a piece, clutched directly to her center of gravity for the spin. She has started to spin at 120 rpm(12.57 rad/sec) and suddenly extends her hands with the bar bells straight out radially from her body. Her arms are 2.5 feet long, her lo=8 lb-ft²(before extension). How much did she increase her mass moment of inertia by after she extended her arms? Answer in Ibm-ft².

A yo-yo is made of two uniform disks, each of mass M and radius R, which are glued to a smaller central axle of negligible mass and radius 0.5R (see figure).
