Question

After spending the entire school year inside working hard at the university you decide to work outdoors in the summer so you take a job of picking fruit in an orchard.The farm provides you with a cart and a small tractor to haul the fruit from the orchard to the truck.the cart consistsof a simple box to carry the load and a single axle with two wheels.the axel is attached to the box using a leaf spring(k).While running this cart back and forth you have a few problems.the main problem is u have to drive over a curb and since u like to drive fast hitting this curb ends up bouncing half the fruit out of the cart.Cart masses 450kg fully loaded(with fruit).displacement of the spring is 5 cm between loaded and free length.You decide to model the cart as a planer model (ie u ignore the cart dynamics & collapse the two tyres & spring into one)& ignore the mass & dynamics of the cart tyres.
Propose a model for the system an write the charecteristic eqation for this model

Answer 1

You have described a problem involving an open box - a partial containment system. The model ,L, for its modification would be of the same dimensions as the top edges of that box. The formula for the model is L = HxW where H is one dimension of the top of the box and W is the other. The model "L" would be built to these dimensions. We would call "L" a Lid and would recommend that it be attach to cover the top of the box with two elastic straps. We will then have designed a model for a simple adaptation whereby a complete containment system for bouncing fruit called a total enclosure can be provided in a practical manner. Engineers do stuff like that, too.

All i desire for Christmas is my 2 front tooth ( I had an accident years in the past and the front have porcelin caps that would desire to get replaced in approximately 2 months while i might desire to have saved adequate funds to alter them!)
