1. Consider a beam pivoted at point A with a cantilevered end at B. The weight of the beam is 30-1b, and one end is supported with a vertical spring (k = 1,800 lb/in) compressed 1 inch, to keep it in a horizontal position. If the beam is released from rest at this position, use the conservation of energy method to determine the angular velocity at the instant it becomes vertical. Assume the beam can be treated as a slender...

The diagram shows a thin rod of uniform mass distribution pivoted about one end by a pin passing through that point. The mass of the rod is 0.460 kg and its length is 1.50 m. When the rod is released from its horizontal position, it swings down to the vertical position as shown. A thin rod labeled M is initially horizontal, with a pivot on its left end. The rod then rotates clockwise by its left end until it is...

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...
