Forces And Pressure | 3 Flashcards
1
Q
Moment
A
Force x perpendicular distance
2
Q
Load
A
Spring constant x extension
(when objects elastic limits is surpassed , permeant change occurs)
3
Q
Pressure
A
Force / Area
4
Q
Pressure in liquid
A
DGH (density , gravity ,height)
5
Q
What are the conditions for a object to be in equilibrium
A
Clockwise moment = Anti - Clockwise moment
Resultant Force = 0
6
Q
What makes a object hard to topple
A
High surface area and low center of gravity
7
Q
Atmospheric pressure conversions
A
1 Atm = 1000 milliba = 100 000 pa
