DYNAMICS OF RIGID BODIES Name: Mech Section: HW-39 1. This problem revisits the "block-and-spool problem" from the tutorial Dynamics of rigid bodies. A block and a spool are each pulled across a level, Top view frictionless surface by a string, as illustrated in the top-view Start Finish diagram at right. The string pulling the block is tied to a hook (not shown) at the center of the front of the block. The string pulling the Blocki spool is wrapped many times around the spool and may Same Same unwind as it is pulled. inertia tension The block and the spool have the same inertias. The strings ON start pulling with the same constant force at the same instant. Spool! Assume that the inertias of the strings and the hook are negligible. a. In the spaces provided, draw and label Free-body diagram Free-body diagram free-body diagrams for the block and for block for spool spool at an instant while the strings are being pulled. b. While the block and spool are being pulled, is the magnitude of the acceleration of the block greater than, less than, or equal to that of the spool? Explain
