The 10 N cylinder moves in a friction tube. Spring constants are k1 = 150 N / m and k2 = 200 N / m. When the system is at rest, d = 0.5 m. The system rotates around a fixed z-axis. In the case where d = 0.12 m, what is the coefficient of friction for the cylinder to have a constant velocity of 9.825 m / s?
Solve it correctly please. I will rate accordingly.
The position of the small 0.68-kg blocks in the smooth radial slots in the disk which rotates about a vertical axis at O is used to activate a speed-control mechanism. If each block moves from r = 162 mm to r = 200 mm while the speed of the disk changes slowly from 272 rev/min to 382 rev/min, design the spring by calculating the spring constant k of each spring. The springs are attached to the inner ends of the slots and to the blocks.

- The 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?
