Unformatted text preview: 3. A section of pipe weighing 48.3 lb rolls without slipping with angular velocity ω 1 before falling into a 14-in. gap (a pot hole) as shown in Fig. 3. If impact at the gap is perfectly plastic and the pipe rolls with ω 2 = 4 rad/s after having climbed up the gap to the other side, determine its angular velocities ( a ) ′′ ω just after impact, ( b ) ′ ω just before impact, ( c ) ω 1. Fig. 3 Fig. 4 4. A section of thin semicircular shell of mass m and mean radius r rests at the bottom of a cylindrical surface of radius R as shown in Fig. 4. If the shell rocks without slipping on the surface, determine its frequency of small-amplitude vibration....
