Chapter D3, Problem D3/044 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 0 = 3.5 rad/sec. If a 0.13-1b particle is sliding in the tube toward O with a velocity of 6.0 ft/sec relative to the tube when the position = 49° is passed, calculate the magnitude N of the normal force exerted by the wall of the tube on the...

Chapter 3, Practice Problem 3/115 The quarter-circular hollow tube of circular cross section starts from rest at time t = 0 and rotates about point o in a horizontal plane with a constant counterclockwise angular acceleration 7 = 2.9 rad/s2. At what time t will the 0.30-kg particle P slip relative to the tube? The coefficient of static friction between the particle and the tube is us = 0.53. 0.58 m 51 Answer: t = the tolerance is +/-2%

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...

The disk rotates about a fixed axis through point o with a clockwise angular velocity wo = 20 rad/s and a counterclockwise angular acceleration 0o = 4.1 rad/s2 at the instant under consideration. The value of r is 260 mm. Pin A is fixed to the disk but slides freely within the slotted member BC. Determine the velocity and acceleration of A relative to slotted member BC and the angular velocity and angular acceleration of BC. The relative velocity and...
