The cone is rotating at a constant angular velocity about the vertical z-axis such that the block attains a speed of 0.6 m/sec.

Prior to rotation, each of the 0.52-kg sliding blocks has the position x = 28 mm with no force in its attached spring. Each spring has a stiffness of 430 N/m. Determine the value of x for each spring for a steady speed of 279 rev/min. Also calculate the normal force N exerted by the side of the slot on the block. The force N is positive if it pushes from the side labeled A. Neglect any friction between the blocks and the slots, and neglect the mass of the springs.

- C14-2. As the large ring rotates, the operator can apply a breaking mechanism that binds the cars to the ring, which then allows the cars to rotate with the ring. Assuming the passengers are not belted into the cars, determine the smallest speed of the ring (cars) so that no passenger will fall out. When should the operator release the brake so that the cars can achieve their greatest speed as they slide freely on the ring? Estimate the greatest normal force of the seat on a passenger when this speed is reached. Use numerical values to explain your answer.arrow_forward2.

They are hinged together at the lower ends and are supported at the upper ends by small rollers of negligible mass which roll on a horizontal rail. Determine the steady state angle assumed by the bars when they are accelerating under the action of a constant horizontal force FN.

- Also include free body diagramarrow_forwardTwo bodies A and B, each weighing 96.6 lb, are connected by a rigid bar of negligible weight attached to them at their gravity centers. The coefficient of friction at the wall and floor is 0.268 if the bodies start from rest at the given position, determine the acceleration of B at this instant. Simplify the solution by creating dynamic equilibrium and taking a moment summation about the intersection of the wall and floor reactions. Explain why these reactions pass through the gravity center of B and A respectively.arrow_forwardThe body A with a mass of 50 kg is in equilibrium with the help of the pulling force generated in the AB and AC cables in the middle of the inclined plane and the friction force between the curved surface and the object. The friction force is on the line of motion of body A and develops in the opposite direction to the movement in the direction of the arrow shown in the drawing. Since the pulling force in AB and AC cables is 15.1 and 22.1 N, respectively, calculate the balancer friction force acting on the object vectorially? (g = 9.81 m / s'2)arrow_forward
