A crane is placed along the easterly sideline of a building, but 25 feet from the front of the building. The building to be erected is a 6 story building that is 100 feet wide by 50feet deep. YOu may assume that each story is 15 feet. The shakeout ple for the structural steel is located 50 feet west of the crane, but on a line with the centerline of crane.
A. what is the minimum legth needed for the boom of the crane in order for the crane to reach the shakeout
B. what is the minimm length needed for the boom of the crane in order for the crane to reach the northeast corner of the 6th floor? (NOte: you may assume that the bottom point of the boom is located at ground leve and you will need a 10 foot clearance between the end of the boom and the floor of the 6th floor.)
C. What is the angle that is formed by the crane boom when it is in the position in Part B?
