P.3) A thoughtful king once decided to update the drawbridge of his castle by attaching the middle of the drawbridge to the castle wall via a single linear spring with an unstretched length of 6 m. The drawbridge is 12 m long, has a rotational inertia of about O of 21,600 kg-m², and has a mass of 450 kg. The king has decreed that the spring constant shall be 690 N/m. What's the velocity with which the end of the drawbridge will strike the ground if it's released from a nearly vertical position?

Conservation of Energy

In physics, the rule of the conservation of energy states that energy doesn’t disappear from the atmosphere; instead, it changes its form from one type to another. Energy is one of the most important physical quantities in nature, and it cannot be created or destroyed — only transformed.

Question

P.3)
A thoughtful king once decided to
update the drawbridge of his castle by attaching the
middle of the drawbridge to the castle wall via a single
linear spring with an unstretched length of 6 m. The
drawbridge is 12 m long, has a rotational inertia of about
O of 21,600 kg-m², and has a mass of 450 kg. The king has
decreed that the spring constant shall be 690 N/m. What's
the velocity with which the end of the drawbridge will
strike the ground if it's released from a nearly vertical
position?

Consider a hollow clay cylinder, which has a moment of inertia 87 kg-m2. The cylinder is free to rotate frictionless-ly, and it starts from rest. It rotate about a fixed axis through its center. Let's assume that we apply a tangential force to the end of the cylinder (the flat face of the shape) with a magnitude which can range from F = 0 to F = 61 N. The force can be applied at any distance from the axis of the cylinder ranging from R=0 to R=4 m from the axis of rotation. (a) Find a pair of values of F and R that cause the disk to complete 2.00 rev in 10.0 s. (b) Is your answer for the previos part unique? How many answers exist?
A windmill turns a series of slender rods fixed about one end (see formula below). They are initially 2 meters long, and go at a speed of 15 rpm. I suggested making the blades 1m long to reduce the cross-sectional area of the windmill, keeping the mass the same for mechanical stress consistency. How fast are the windmill blades going now, in revolutions per minute?
