uh oh. i’m a bad teacher then :(.

stress = F/A where F = force applied, A = area over which force is applied, and stress is often denoted as the greek lowercase letter, sigma.

F = ma is the formula for force (as mentioned above) where F = force applied (often referred to as the “load”), m = mass of the object, a = acceleration the object is experiencing.

:(.

rebeccachai:

from karen, i learned that f=ma is the formula for stress! =) don’t stress out. =P

When F=ma is a surprise to a mechanical engineering graduate student, that’s when the studying has to stop and brain resting take over.
