Question

Sir lost a lot dons his armor and sots out from the castle on his trusty steed (see figure below). Usually, the drawbridge Is lowed to a horizontal position so that the end of the bridge rests on the stone ledge. Unfortunately lost-a-U>>t*s squire drdnt lower the drawbridge far enough and stopped it at theta =  20.0 degree above the horizontal, the knight and his horse stop when their combined center of mass is d = 1.00 m Irom the end of the bridge, the uniform bridge is/= 6.00 m long and has a mass of ) 200 kg. The lift cable Is attached to the bridge 6.00 m from the hinge at the castle end and to a point on the castle wall h = 12.0 m above the bridge, lost a lot's mass combined with his armor and steed Is 850 kg. Determine the tension In the cable. Determine the horizontal force component acting on the bridge at the hinge, magnitude direction Determine the vertical force component acting on the bridge at the hinge, magnitude magnitude direction

Explanation / Answer

Assuming the mass of the bridge to be 2200 kg and mass of rider + his accessories to be 850 kg.

(a) T = 24841.78 N

(b) F_x = 8496.39 N

(c) F_y = 7156.36 N
