How were drawbridges and portcullises used tactically? How were drawbridges and portcullises used tactically? I was recently asked why medieval castles would have both a drawbridge and a portcullis After giving an explanation, I realized that it was j
High Quality SOLUTION A uniform drawbridge must be held at a 37 . . . - Chegg Question: A uniform drawbridge must be held at a 37∘ angle above the horizontal to allow ships to pass underneath The drawbridge weighs 45,000 N and is 14 0 m long A cable is connected 3 5 m from the hinge where the bridge pivots (measured along the bridge) and pulls horizontally on the bridge to hold it in place Part AWhat is the tension in the cable?Express
Solved A drawbridge is being held stationary. Thisdrawbridge - Chegg A drawbridge is being held stationary Thisdrawbridge is 10 m long and has a mass of270 kg It is attached at its base to a stone wallwith a hinge The drawbridge is uniform, so itscenter of gravity is exactly at its (geometric)center The drawbridge is being fixed by a chainattached 2 0 m from the end of the bridge
Solved Problem 10 (Stabilizing a drawbridge) A drawbridge is - Chegg Problem 10 (Stabilizing a drawbridge) A drawbridge is being held stationary This drawbridge is 10 m long and has a mass of 270 kg It is attached at its base to a stone wall 2 0 m with a hinge The drawbridge is uniform, so its center of gravity is exactly at its (geometric) 40° center
Solved Problem 4 In ancient times drawbridges were commonly - Chegg Science Physics Physics questions and answers Problem 4 In ancient times drawbridges were commonly used at the entrance of a castle Drawbridges were usually kept raised only about half way This cut down on the time needed to lower the bridge to let commerce in or raise it to prevent attack In the diagram below a 12 m drawbridge, mlridge =2100 kg, is raised to a 40∘ angle The bridge is
Problem 8 (Stabilizing a drawbridge)A drawbridge is - Chegg A drawbridge is being held stationary This drawbridge is 1 0 m long and has a mass of 2 7 0 k g It is attached at its base to a stone wall with a hinge The drawbridge is uniform, so its center of gravity is exactly at its (geometric) center The drawbridge is being fixed by a chain attached 2 0 m from the end of the bridge
Solved Suppose the weight of the drawbridge in the figure - Chegg Question: Suppose the weight of the drawbridge in the figure below is supported entirely by its hinges and the opposite shore, so that its cables are slack (b) What is the magnitude in newtons and direction of the force the hinges exert on the bridge under these circumstances? The mass of the bridge is 2,625 kg
