Question

2. How much is the maximum weight that this crane can lift (to avoid above issue) if the total weight of crane (itself) is 1200 lb, its height is 75 ft and the length of its arm (crane's boom) is 50 ft. The contact area between crane and the ground is a square shape (8 ftX8ft). Attach your calculation to the post. (hint: tensile stress causes the detachment of the crane from the ground) (5 points)
