For large and stronger structures use the ball or explosives, see,

Calculate the peak force generated when a 1 ton ball moving at 15 ft per second stops within 1 inch. If I did it right I get about 90,000 lbs. force concentrated over a relatively small area. It would be difficult to apply such a force many stories up with machines we have.
Wrecking balls are able to cause more damage than other demolition methods because of their high impact force. When the ball swings and collides with a building, the kinetic energy is transferred to the structure, causing it to weaken and eventually collapse.
The size of the wrecking ball plays a crucial role in the amount of damage it can cause. A larger wrecking ball has more mass and therefore more kinetic energy when it swings, resulting in a more powerful impact and greater damage to the structure.
Yes, wrecking balls can be controlled to cause specific damage. The crane operator can adjust the trajectory and force of the swing to target specific areas of the building. This allows for precise demolition and minimizes collateral damage.
Wrecking balls are often attached to cranes or other machinery to provide stability and control during the demolition process. The attached wrecking ball helps to guide the swing and ensures that it hits the intended target with maximum force.
Yes, there are risks associated with using wrecking balls for demolition. If not properly controlled, the wrecking ball can cause damage to surrounding structures or injure workers. It is important to have experienced and trained professionals operating the machinery to minimize these risks.
