In one of the photos at the beginning of this chapter, Mary Beth uses a torque feeler that consists of a meterstick held at the 0-cm end with a weight dangling from various positions along the stick. When the stick is held horizontally, torque is produced when a 1-kg object hangs from the 50-cm mark. How much more torque is exerted when the object is hung from the 75-cm mark
