3. The hollow tube is pivoted about a horizontal axis through point O and is made to
rotate in the vertical plane with a constant counterclockwise angular velocity of 3
rad /sec. If a 0.2-lb particle is sliding in the tube toward 0 with a velocity of 6 ft /sec
relative to the tube when the position 0 = 30° is passed, calculate the magnitude N
of the normal force exerted by the wall of the tube on the particle at this instant.
The 1-meter long, 10-kg slender rod is released from rest when it is completely horizontal. The sliders move along frictionless guides and the spring attached to end A has a constant of k = 3 kN/m. If the spring is compressed by 300 mm when the rod is horizontal, find the angular velocity of the rod and the velocity of end A when the rod is at the position shown.
The two 11-kg slender rods are pin connected and
released from rest at the position 0 = 60°. Neglect the
mass of the roller at C. (Figure 1)
