Formula of density

d = m/V where m is mass and V is volume

1

The property of material in a state of deformation to retain its original shape when an applied force on it is removed.

Elasticity

2

Stress where two linear forces act away from the object.

Tensile Stress

3

Stress where two linear forces act towards an object

compressive stress

4

Stress where two contacting surfaces exert forces tangent to each other. Tends to deform an object sideward.

Shearing stress

5

Maximum stress to which a solid can be subjected without being permanently altered.

Elastic limit

6

The greatest tension a rod can withstand and corresponds to the highest point on the curve

ultimate strength

7

can be deformed a great deal beyond their elastic limits, has a large plastic range in tension

ductility

8

Has a large plastic range in compression

malleable metal

9

the greatest shear stress an object can withstand before breaking

shear strength

10

lack of coincidence of the curves for increasing and decreasing stress

elastic hysteresis

11

formula for power output

Po = dgh(V/t)

12

formula for power input

Pi = Po/Eff

13

Formula for stress



S = Force/ area

14

Formula for specific gravity

Sg = density of substance/density of water

15

Formula for Young's modulus

Y= (force/area)/(change in length/initial length)

16

This law states that a force applied at one of the spring is directly proportional to the springs elongation

Hookes law
