What does ut tensio sic vis mean?

"Ut tensio, sic vis." is a Latin phrase that translates to "As the tension, so the force." This phrase is used to express the idea that the force exerted by a spring or other elastic object is directly proportional to its degree of tension or stretching. In other words, the more you stretch a spring, the greater the force it will exert when released. This principle is known as Hooke's law.
