new teaser
a stress of 3.2MN m -2 is applied to a sample of material.
this requires a force of 80N.
use the following formula to calculate the area over which that force acts.
note MN m-2 is equal to N mm-2 so u dont need to do any unit conversions.
you will need to rearrange the formula
STRESS= FORCE/AREA.
