Three small blocks, each with mass .65 kg, are clamped at the ends and at the center of a rod of length 2.4 m and negligible mass. Compute the rotational inertia of the system (in kgm2) about an axis perpendicular to the rod and passing through the center of the rod.   What is the rotational inertia if the thing is pivoted about one end?   Compute the rotational inertia of the system about an axis perpendicular to the rod and passing through a point one-fourth of the length from one end.

The class I'm taking is physics for scientists and engineers! Need help. I have attached the problem.  Thank you so much!

The uniform solid block in the figure has mass 27.6 kg and edge lengths a = 0.971 m, b = 1.43 m, and c = 0.118 m. Calculate its rotational inertia about an axis through one corner and perpendicular to the large faces.

A meter stick of mass m, = 0.25 kg rotates about an axis passing through one end as shown in figure below. The rotational inertia of the meter stick I, = 0.09 kgm2. As the stick reaches its lowest position, it collides with a m, = 0.15 kg putty that sticks to the end of the meter stick. The stick's angular speed just before collision is w, = 2.1 rad/s, what is the angular speed of the stick-putty system immediately after collision? %3D Assume length of rod = 1 %3D

A solid cylinder with mass m, radius R, and rotational inertia I (about its center) is released from rest and rolls down a ramp.  Friction between the bottom of the cylinder and the ramp causes the cylinder to roll without slipping.  The linear acceleration of the cylinder is a.  Which TWO of the equations below are correct for this scenario? The equations are in terms of m, I, R, and a, as well as f (the force of static friction between the cylinder and the ramp) and g.  (You must pick BOTH of them to get this question correct!) f = ma mg sin θ = ma mg sin θ - f = ma f R = I (a/R) mg sin θ - f = I (a/R) R mg sin θ = IaR
