A spring balance is hung from the ceiling by means of a long rope. A second rope is attached to the spring balance, pulled tight so the balance reads 100 pounds, and then anchored to the floor. If a 60-pound weight is then hung on the hook of the balance, what will the balance read?

The balance will read 100 pounds. You can put up to 100 pounds on the hook before the rope will slacken and the hook will start to move downwards, changing the figure on the balance. Dec 09 02, 8:32 PM
