Rod OA rotates counterclockwise with an angular position - 2t rad, where t is in seconds. The double collar B is pin-connected together such that one collar slides over the rotating rod and the other collar slides over the circular hoop rod described by the equation r = 1.6cose m. If the total mass of both collars is 0.5 kg and of the rod and hoop are negligible, when = 30° which takes t = ()(180) sec, determine the circumferential acceleration of the collars, ag.

An inclined plane of angle e = 20.0° has a spring of force constant k = 510 N/m fastened securely at the bottom so that the spring is parallel to the surface as shown in the figure below. A block of mass m = 2.61 kg is placed on the plane at a distance d = 0.297 m from the spring. From this position, the block is projected downward toward the spring with speed v = 0.750 m/s. By what distance is the spring compressed when the block momentarily comes to rest?
The sphere of mass m1 = 5 kg falls from a height H = 1.4 m onto the homogeneous board of negligible mass. The board can rotate around a horizontal axis passing through point O, and a body of mass m2 = 3.9 kg is placed on it at a distance b = 1 m from the axis of rotation. The collision is perfectly inelastic. How high does the body of mass m2 rise after the collision (in m) if a = 0.5 m?

Dynamic Analysis and Aeroelasticity Figure 2 shows a homogeneous circular disk with radius R and mass m as it is released from rest on an inclined surface. The moment of inertia of the disk about its centre is IG = mR². Determine the disk's angular acceleration as it rolls down the surface. R В ENG2012-N Figure 2 - Disk on an Inclined surface.
The figure shows a small piece of clay colliding into a disk. The disk is initially at rest, but can rotate about a pivot fixed at its center. The collision is completely inelastic.The disk has mass M = 4.73 kilograms and radius R = 0.755 meters. The clay has mass m = 279 grams and is moving horizontally at vi = 3.66 m/s just before colliding with and sticking to the disk. The clay strikes the edge of the disk at a location of b = 0.505 meters offset from the center of the disk. Note that the size of the clay is negligible compared to the radius of the disk. Calculate the angular velocity (rad/s) of the disk just after the collision.

The three masses in the figure are different. The planes do not have friction with the masses and the plane of mass 3 corresponds to a quarter of a circumference. All three masses are released at the same time. The masses m2 and m3 travel the same distance. The first mass that will reach the bottom of the ramp will be: m1 m2 m3 m2 and m3 m1 and m2 m1 and m3 they will all arrive at the same time
The armature (slender rod) AB has a mass of 0.2 kg and can pivot about the pin at A. Movement is controlled by the electromagnet E, which exerts a horizontal (0.2(10-3)/) N, attractive force on the armature at B of FB where I in meters is the gap between the armature and the magnet at any instant. If the armature lies in the horizontal plane, and is originally at rest, determine the speed of the contact at B the instant I = 0.01 m. Originally I = 0.02 m. B В 150 mm E« A
