Prob. 1.4-11. A log that weighs 3600 lb and is 30 ft long is being
hoisted by a cable that passes over two pulleys, as shown in
Fig. P1.4-11. In the position shown, the cable from the log to the
first pulley is vertical, and the log is inclined at an angle of 30°
to the ground. Assume that neither the ground nor the block at A
provides any moment restraint, and neglect the radial distance
from the center of the log to the two points of contact at A.
