Turning Force Or Moment Flashcards
What is moment
The turning force - like a door handle
Moment formula
Moment= force x perpendicular distance from pivot
When is an object equilibrium
When there is no resultant force & no resultant moment an object is in equilibrium
What is the principle of moments
when a body is balanced, the total clockwise moment about a point equals the total anticlockwise moment about the same point
How do you find the centre of gravity on a regular shape
It tends to be in the middle
What is the centre of gravity
The point at which the entire weight of an object acts
How do you find centre of gravity on irregular shaped objects
suspension method: Suspend the object from different points and draw vertical lines from the suspension point. The intersection of these lines
Pressure formula
P = force/ area
Pressure unit
Pa or N/m2
