The trailer has a mass of 580 kg and a mass center at G. The spool has a mass of 200 kg with a mass center at O and a radius of gyration about an axis passing through 0 and 0.45 m. If a force of 60 N is applied to the cable, determine the angular acceleration of the spool and the acceleration of the trailer. The wheels have negligible mass and are free to rotate.
A fluid flowing in a pipe 30cm in diameter has a uniform velocity of 4m/s. The pressure at the center of the pipe is 40KPa, and the elevation of the pipe's centerline above an assumed datum is 4.5m. Compute the total energy per unit weight of the ..
