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 A dancer is standing on one leg on a drawbridge that - Chegg Question: A dancer is standing on one leg on a drawbridge that is about to open The coefficients of static and kinetic friction between the drawbridge and the dancer's foot are μs and μk, respectively n⃗ represents the normal force exerted on the dancer by the bridge, and F⃗ g represents the gravitational force exerted on the dancer, as shown in the drawing (Figure
Solved Sir Lost-a-Lot dons his armor and sets | Chegg. com Usually, the drawbridge is lowed to a horizontal position so that the end of the bridge rests on the stone ledge Unfortunately Lost-a-Lot's squire didn't lower the drawbridge far enough and stopped it at θ = 20 0° above the horizontal The knight Sir Lost-a-Lot dons his armor and sets out from the castle on his trusty steed (see figure below)
Where is (or was) the biggest medieval drawbridge? The purpose of the drawbridge was to deny access to the castle gate As such, spanning large distances was not usually necessary, at least by the drawbridge itself The still-operational drawbridges at Helmingham Hall are a good example: The moat is up to 18m wide by 1 8m deep
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
