A slender 9 lb rod can rotate in a vertical plane about a pivot at B. A spring of constant k-30 lb/ft and of unstretched length 6 in. is attached to the rod as shown. The rod is released from rest in...
Problem 9 (15 points) A 20-lb slender rod AB is 5 ft long and is pivoted about a point O which is 1 ft from end B. The other end is pressed against a spring of constant k-400 lbin until the spring is compressed 2 in, and the rod is in a horizontal position. If the rod is released from this position, determine its angular velocity and the reaction at the pivot O as the rod passes through a thirty...
A 24 lb uniform slender rod AB of length L= 36 in is fixed to a 12 lb uniform disk of radius, R= 12 in , and both are pinned at B as shown. A belt is attached to the rim of the disk and then to a spring with spring constant, k= 40 lb/in which holds the rod/disk at rest in the equilibrium position shown. natural period is 0.446 s If end A is displaced a distance of 0.9...
Sample Problem 6. The 30 kg slender rod is released from rest when θ-00 (when rod OA is in the horizontal position). The spring is unstretched at θ-00. A constant clockwise moment of 10 N-m is applied to the rod. A force, P, of 20 N is applied and is always perpendicular to the rod. Determine the angular velocity of the rod when θ- 750. (Use the work-energy or conservation of energy method). 2 m 10 N-mm k80 N/m 1.5...
4. The pendulum in Figure 4 consists of a 10 lb sphere of radius 1.0 f and a 5 lb slender rod of length 2.0 ft. Determine: (10 pts) the angularacceleration of the pendulum immediately after the string is cut and the reaction at the pin support O a. b. (10 pts) Using Work-Energy determine the angular velocity of the pendulum as it swings through the vertical position and the reaction at the pin O at that instant. BC 1...

A thin rod, of length L and negligible mass, that can pivot about one end to rotate in a vertical circle. A heavy ball of mass m is attached to the other end. The rod is pulled aside through an angle and released. (a)What is the speed of the ball at the lowest point if L = 2.20 m, = 19.0°, and m = 500 kg? (b) Does the speed increase, decrease, or remain the same if the mass is...
