The 35 lb slender rod AB is 277 in. long and at rest in a horizontal position supported by a spring located at h = 226 in. from the suspension cable at B. If the cable at B fails, answer the following 1) Part A: Determine the magnitude of the acceleration of end A. 2) Part B: Determine the magnitude of the acceleration of end B. 3) Part C: Determine the angular acceleration of the rod.
The rod AB has a mass of 20 kg，the mass of the piston A and B are both 5kg. Piston B is attached to a spring of constant k = 1200 N/m. The spring is un-stretched when θ = 0. If the rod is released from rest whenθ = 45° Please find÷ (1) the moment inertia of the rod AB about its mass center G (2)The angular velocity of rod AB at θ = 0° (3）the velocity of piston A at θ = 0° (4) the velocity of Piston B at θ = 0° (hint: regard the piston A, B, rod as a system, during the motion, except the spring, the weight of rod AB, the weight of pistonB also does work). g = 9.8 m/s2
૨૩: If P = 200 N and the 15-kg uniform slender rod starts from rest at 0 = 0°, determine the rod's angular velocity at the instant just before 0 = 45°. Ans.: @₂ = 4.97 rad/s 45° 600 mm P = 200 N SOC
Two uniform cylinders, each of mass m= 9.5 kg and radius r= 125 mm, are connected by a belt as shown. The system is released from rest when t = 0. B A Determine the velocity of the center of cylinder A at t = 4.4 s. The velocity of the center of cylinder A is 3 m/s ↓.
Rod AB and body C each have a mass m. The system is released from rest when 00. Determine the distance x which will result in the maximum angular ac- celeration of rod AB and the resulting angular acceleration when 0 = 30º. (Draw FBDs)
A bar weighing 2 lb per ft is bent at right angles into segments 26 in. and 13 in long. It takes to the position shown in Fig. P-1086 when the frame F to which it is pinned at A is accelerated horizontally. Determine this acceleration and the components of the reaction at A.
