Two panels A and B are attached with hinges to a rectangular plate and held by a wire as shown. The plate and the panels are made of the same material and have the same thickness. The entire assembly is rotating with an angular velocity w0 when the wire breaks. Determine the angular velocity of the assembly after the panels have come to rest against the plate.
A pair of rods and disc form a triangle with a spring (a spring connects A to C). The spring has a spring constant of 20 N/m and an unstretched length of 1.5m. each rod has a length of 3m and a mass of 10kg. The disk has a mass of 5kg, a radius of .5 and rolls without slipping. The system starts with an angle between the spring and rods of 60 degrees, determine the angular velocity of the rods after it has dropped to a 30 degree angle.
A slender 9-lb rod can rotate in a vertical plane about a pivot at B. A spring of constant k = 21 lb/ft and of unstretched length 6 in. is attached to the rod as shown in the figure. Knowing that the rod is released from rest in the position shown in the figure, determine its angular velocity after it has rotated through 90 degree .
