Find the principal moments of inertia about the center of mass of a flat rigid body in the shape of a 45 degree right triangle with uniform mass density. What are the principal axes?
What is the rotational inertia of a solid iron disk of mass 49 kg, with a thickness of 5.00 cm and radius of 20.0 cm, about an axis through its center and perpendicular to it?
hree 0.57 kg particles form an equilateral triangle with 0.51 msides. The particles are connected by rods of negligiblemass.What is the rotational inertia of this rigid body about an axisthat passes through one of the particles and is parallel to the rodconnecting the other two?
