Twenty people participate in a tug-of-war. The two teams of ten people are so evenly matched that neither team wins. After the game they notice that a car is stuck in the mud. They attach the tug-of-war rope to the bumper of the car, and all the people pull on the rope. The heavy car has just moved a couple of decimeters when the rope breaks. Why did the rope break in this situation when it did not break when the same twenty people pulled on it in a tug-of-war?

They attach the tug-of-war rope to the bumper of the car, and all the people pull on the rope. The heavy car has just moved a couple of decimeters when the rope breaks. Why did the rope break in this situation when it did not break when the same twenty people pulled on it in a tug-of-war?

To determine

The reason that cause the breaking of the rope.

Explanation of Solution

When the rope was used in a tug of war, a force is applied on the rope, which is under the safety factor of the rope, as rope was designed to bear such force. But when the same rope was used to pull car by twenty people, all the twenty people exerted the force on the rope from one side and from the other side car weight is putting more tension on to the rope...
