a mas-spring model of the type used to design packaging systems and
vehicle suspensions, for example. The springs exert a force that is proportional to their
compression, and the proportionality constant is the spring constant k. The two side
springs provide additional resistance if the weight is too heavy for the center spring.
When the weight W is gently placed, it moves through a distance x before coming to
rest. From statics, the weight force must balance the spring forces at this new position.
W =?1?; if x < d
W = ?1? + 2?2(? − ?); if x ≥d
Create a function file that computes the distance x, using the input parameters W , , ?2
, ?1 and d. Test your function for the following two cases, using the values ?1 = 10
kN/m ; ?2 = 15 kN/m ; d = 0.1 m.
W = 500 N
W = 2000 N
