the total force that u are exerting will be equal to the buoyant force + the force exerted by the pressurised air inside the cup. the buoyant force wil be propotional to volume of CUP(not the inside hollow),ie the priphery which is submerged in the liquid and the force exerted by the air inside...
i am trying to simulate the spiralling motion of a coin that is rolled on a table.i am having three equations...
1. the gyroscopic moment equation.
2. the conservation of energy equation.
3. general kinematic equation.
three unknowns...curvature radius,precession velocity and coin...
find the final momentum in the x and y directions.they must be equal to the initial momentum.
final momentum in x direction = M* v(x) = m1*v1(x) + m2*v2(x)
final momentum in y direction = M* v(y) = m1*v1(y) + m2*v2(y)
u know M=m1+m2, m1,m2 and v1 and v2.
find v(x) and v(y).
I am planning to make a go-kart.could someone help me with the design paramaeters?I would like to have a complete idea on the design of the frame (by this i mean to understand the pros n cons of front taper etc used in modern race cars),suspensions etc.
I have gone through much of the...
I think u don't have to finish off the extinguisher.once u attain a good velocity u don't have to spray more as in space since there is no air,so u won't be slowed down.so u need to spray more only for a change of direction.
i think the door will not move on its own unless there is some amount of wind to push it.shyboy said that it will move provided the centre of gravity moves down as it rotates.such a situation is called an unstable equilibrium...ie just a little push is required is needed to get it moving and...
usually basic GK questions r asked...like the preamble,fundamental rights etc.also some subject knowledge in history,chemistry,geography.U must be able to introduce yourself well and get to know how to lead the interview.
