Ageostationary satellite has an 8kw rf transmission pointed at the earth. how much force does that induce on the spacecraft? (n)

The force induced on the aircraft is 2.60 N

Solution:

As per the question:

Power transmitted,

Now, the force, F is given by:

              (1)

where

v = velocity

Now,

For a geo-stationary satellite, the centripetal force, is provided by the gravitational force, :

Thus from the above, velocity comes out to be:

where

R =

R =

where

G = Gravitational constant

T = Time period of rotation of Earth

R is calculated as 42166 km

Now, from eqn (1):

F = 2.60 N

can you make it more obvious. i can't see it properly

unlike the threaded fasteners which are used to clamp the machine members, power screws are used to transmit power. common applications of power screws are: screw jacks: to lift weight. lead screw of lathe: for axial movement of tool and its precise positioning.
