Flashcards in Module 1 Deck (17):
Formula of density
d = m/V where m is mass and V is volume
The property of material in a state of deformation to retain its original shape when an applied force on it is removed.
Stress where two linear forces act away from the object.
Stress where two linear forces act towards an object
Stress where two contacting surfaces exert forces tangent to each other. Tends to deform an object sideward.
Maximum stress to which a solid can be subjected without being permanently altered.
The greatest tension a rod can withstand and corresponds to the highest point on the curve
can be deformed a great deal beyond their elastic limits, has a large plastic range in tension
Has a large plastic range in compression
the greatest shear stress an object can withstand before breaking
lack of coincidence of the curves for increasing and decreasing stress
formula for power output
Po = dgh(V/t)
formula for power input
Pi = Po/Eff
Formula for stress
S = Force/ area
Formula for specific gravity
Sg = density of substance/density of water
Formula for Young's modulus
Y= (force/area)/(change in length/initial length)
