 | | Suppose that the force in a cable of a suspension bridge is 10000000 Newtons, or 10 megaNewtons, that is, 10 MN, and the cross-sectional area is 0.25 square metres. |
 | | To make this easier to visualize, one Newton is roughly the weight of 0.1 kilogram, so a kiloNewton is about the weight of 0.1 tonne, and a megaNewton corresponds to about 100 tonnes. |
 | | More exactly, 1 kg weighs about 9.8 N. If we were to reduce the area of the cable to 0.1 square metre, the stress would increase to 100 MN/m |
