2. Figure 2 shows the mechanism for a door panel held in place by a bar BC and a torsional spring. The door panel has a mass of 30 kg and held in equilibrium at 0 60. It is required to determine the stiffness (k) of the torsional spring such that the door panel reaches the closed position (0-0") with a zero angular velocity once the supporting rod BC is removed. The mass moment of inertia of the door panel...

problem 6: A uniform ladder 12 meters long rests against a vertical frictionless wall, as shown in the figure. The ladder has a weight f400 Nand makes an angle θ 51 0° with the floor. A painter weighing 874 N climbs slowly up the ladder when he is slightly above 2/s of the way up the ladder, the bottom of the ladder will just start to slip. So the painter stops at 7.80 m mark.

5. (20 points) A mass weighing 8 pounds stretches a spring 1.6 feet. The entire system is placed in a medium that offers a damping force numerically equivalent to twice the instantaneous velocity. The mass is initially released from a point 1/2 foot above the equilibrium point with a downward velocity of 5 ft/sec. (a) (6 points) Write the differential equation for the mass/spring system and identify the initial conditions. 7 5. (b) (12 points) Solve the IVP in part...
