Cranes that have telescopic booms may be capable of lifting a heavier load when the boom length and radius is small. if the boom is extended, the weight of the object can the crane.

overload                                                  

Explanation:

            A crane is a kind of machine which is used to lift  heavy loads and transfer loads or objects to other location using hoist rope and chains. It consists of long booms and hoist wire ropes which is attached to the object and is lifted.

           The dimensions and the length of the boom of the crane in an essential measure to determine the quantity  of load to be lifted by the crane. When the  boom of the crane is small in length and they have a small diameter, the crane is not suitable to lift a very heavy object. In this case, the weight of the object overloads the crane.

            In order to lift a very object, the book of the crane should be long enough and the radius of the boom should be more.

Thus the answer is --

overload    

the inner core.
