For 100 Points
A 110 ft. long boom crane
is being used to lift a load close to the crane. The load radius
(distance from the boom hinge to the load) is 20 feet, so the boom angle is 81o. If the entire crane is tipped toward the load by only 5 degrees due to poor leveling, how
much lifting capacity has the crane lost?
a) 10 %, b) 20 %, c) 30 %, d) 50 %.
