Forces And Pressure | 3

Question 1

Moment

Answer 1

Force x perpendicular distance

Question 2

Load

Answer 2

Spring constant x extension

(when objects elastic limits is surpassed , permeant change occurs)

Question 3

Pressure

Answer 3

Force / Area

Question 4

Pressure in liquid

Answer 4

DGH (density , gravity ,height)

Question 5

What are the conditions for a object to be in equilibrium

Answer 5

Clockwise moment = Anti - Clockwise moment

Resultant Force = 0

Question 6

What makes a object hard to topple

Answer 6

High surface area and low center of gravity

Question 7

Atmospheric pressure conversions

Answer 7

1 Atm = 1000 milliba = 100 000 pa
