Centroids and Center of Gravity
Suspended Weight Effect
When a weight is suspended, its center of gravity is considered to be at the point of suspension.
formulas
GG´ = _(w)(d) \ W
d = Kg´- Kg
KG´ = KG + GG´
Transfer Effect
GG´= (w)(d)\W
formula
the center of gravity moove with the cargo in vertical and horizontal tranfer
definition
Center of Gravity
the center of gravity of a body is the point at which all the mass of the body may be assumed to be concentrated and is the point through which the force of gravity is considered to act vertically downwards, with a force equal to the weight of the body. It is also the point about which the body would balance.
Centroids
The centroid of an area is situated at its geometrical centre.
Unloading effect
When a mass is withdrawn from a body, the center of gravity of the body will move in the opposite direction to the center of gravity of the mass withdrawn
Formulas
GG´ = (w)(d)\W-w
KG´ = KG + GG
Loading effect
When a mass is added to a body, the center of gravity of that body will move directly towards the center of gravity of the mass added and the distance that it moves
Formulas
GG´ =(w)(d)\ W+w
d = KG – kg o´
d = kg – KG
KG´ = KG + GG´
