WebMeanwhile, a boat approaches, so the drawbridge is raised by means of a cable attached to the end opposite the hinge (the figure ). The drawbridge is 40.0 long and has a mass of 18,000 ; its center of gravity is at its midpoint. The cement mixer, with driver, has mass 30,000 . When the drawbridge has been raised to an angle of 30 above the
Maximum tension in a cable holding a drawbridge Physics Forums
WebA loaded cement mixer drives onto an old drawbridge, where it stalls with its center of gravity three-quarters of the way across the span. The truck driver radios for help, sets the handbrake, and waits. Meanwhile, a boat approaches, so the drawbridge is raised by means of a cable attached to the end opposite the hinge ($\textbf{Fig. P11.52}$). Medieval castles were usually defended by a ditch or moat, crossed by a wooden bridge. In early castles the bridge might be designed to be destroyed or removed in the event of an attack, but drawbridges became very common. A typical arrangement would have the drawbridge immediately outside a gatehouse, consisting of a wooden deck with one edge hinged or pivoting at the gatehouse threshold, so that in the raised position the bridge would be flush against the gat… knife sharpening el paso
