2. (25 pts) The end A of the garage door AB travels along the horizontal track, and the end of member BC is attached to a spring at C. If the spring is originally unstretched, determine the stiffness k so that when the door falls downward from rest in the position shown, it will have zero angular velocity the moment it closes, i.e., when it and BC become vertical and are also at rest. Neglect...

Consider the system shown in the figure below. The mass moment
of inertia of the bar about the point O is JO, and the torsional
stiffness of the spring attached to the pivot point is kt . Assume
that there is gravity loading. The centre of gravity of the bar is
midways, as shown in the figure.

change in kinetic enegery)
KE20. Figure shows a mechanism. Body 5 is assumed to be homogeneous circular cylinder, and mass of the pulley 4 is uniformly distributed over its rim. The coefficient of sliding friction between bodies and the plane is f 0.1 The coefficient of stiffness of a spring is c. A force F applied to the mechanism depends on the displacement s of the body 1. The mechanism starts motion...

2. (40 points) A soccer ball tester consists of a 15-kg slender rod AB with a 1.1-kg sim- ulated foot located at A and a torsional spring located at pin B. The torsional spring has a spring constant of k 910 N.m/rad and is unstretched when AB is its lowest position. Fig. 2 depicts the simulation. The length of AB is 0.9 m, and you can assume that the foot ban be modcled as a particle, Knowing that the velocity...

The figure shows the cross section AB of a garage door which is a rectangular 2.60-m by 5.4-m panel of uniform thickness with a mass of 145 kg. The door is supported by the struts of negligible mass and hinged at O. Two spring-and-cable assemblies, one on each side of the door, control the movement. When the door is in the horizontal open position, each spring is unextended. If the door is given a slight imbalance from the open position...

(a) A uniform bar BC with one end, B, on the ground has a mass of 15 kg and falls from rest when 0 90°. It strikes the edge at A when 0-60°. If the bar then begins to pivot about this point after contact, determine the bar's angular velocity just after the impact. Assume the bar does not slip at B as it falls until it strikes A. The moment of inertia of the uniform bar about its mass...
