Sir Lost-a-Lot dons his armor and bursts out

of the castle on his trusty steed Tripper in
his quest to rescue fair damsels from drag-
ons. Unfortunately his valiant aide Doubtless
lowered the drawbridge too far and finally
stopped it 30� below the horizontal. Lost-
a-Lot screeches to a stop when his and his
steed’s combined mass (1500 kg) is 1.2 m
from the end of the bridge, which is 7.5 m long with a mass of 2300 kg. The lift cable is
attached to the bridge 3.3 m from the hinge
and to the parapets 9.7 m above the bridge.

Find the tension in the cable. The acceler-
ation of gravity is 9.8 m/s2 .

this is so difficult please help
