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 theta = 3.4 rad/sec. If a 0.19-lb particle is sliding in the tube toward O with a velocity of 4.0 ft/sec relative to the tube when the position theta = 32 degree is passed, calculate the magnitude N of the normal force exerted by the wall of the tube on the particle at...

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 0 = 1.1 rad/s2. At what time t will the 0.57-kg particle p slip relative to the tube? The coefficient of static friction between the particle and the tube is a = 0.69 0.83 m 53 w Answer: ta S the tolerance is +/-2%...

Chapter 3, Practice Problem 3/125 The 52-in. drum rotates about a horizontal axis with a constant angular velocity 4.7 rad/sec. The small block A has no motion relative to the drum surface as it passes the bottom position = 0. Determine the coefficient of static friction Ys which would result in block slippage at an angular position 0; plot your expression for O Ses 180º. Determine the minimum required coefficient value min which would allow the block to remain fixed...
