Question
When testing the landing gear unit of a space
vehicle drop tests are carried out. Figure 2.17 is a
schematic model of the unit at the instant when it
first touches the ground. At this instant the spring is
fully extended and the velocity of the mass is ()
where h is the height from which the unit has been
dropped. Obtain the equation representing the
displacement of the mass at time t>0 when
M=50kg B = 180 Nsm^-1 and k = 474.5 N m^-1, and
investigate the effects of different dropping height
h. (g is the acceleration due to gravity and my be
taken as 9.8 ms^-2.)
and the velocity of the mass is √(2gh), where h is the
height from which the unit has been dropped. Obtain
the equation representing the displacement of the
mass at time t> 0 when M = 50 kg, B = 180 N sm
and K = 474.5 Nm, and investigate the effects of
different dropping heights h. (g is the acceleration
due to gravity, and may be taken as 9.8 m s².)
