## 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)
