... must be doubled as well. Modeling a thick wire as a bundle of thin wires, the preceding argument explains why the force to produce a given strain must be proportional to the cross-sectional area—and thus why the strain depends on the stress. 14. A given tensile stress produces a given stretch in the ...

Force and Laws of Motion
... Effects of force:Some of the common effects of force are:1. A force may move a body at rest. For example, when we kick a football kept on the ground with our foot, the football moves. The force applied by our foot moves the ball. 2. A force may stop a moving body. For example, when a player catches ...
