Calculation of metacentric height of floating body involve second moment of area. The axis about which this moment is to be calculated passes through...
A)top horizontal surface of body
B) Bottom horizontal
C) Center
of gravity
D) center
of buyoncy.
Answer
For a floating body,how is metacentric radius defined..
A) distance between C.G and Metacentre.
B) Second moment of area of plane of floatation about centroidal axis perpendicular to plane of rotation/immersed volume.
C) the distance between C.G and C.B
D)momen of inertia of the body about its axis of rotation/immersed volume.
If any one of the rotational components are not zero while others are zero then flow is rotational or irrotational??
