PLEASE HELP ME HOW CAN I DESIGN PROJECT

The aim of the project:

Your aim is to develop a design of a table tennis machine!

Design and built a new model of a ball launcher$/$catapult$/$trebuchet etc or any other mechanism in order to throw

a ball over a net.

Your mechanism will throw the ball over the net and there will be a circular target area. Your aim is to throw the

ball over the net and hit the target. The ball must do a single bounce before hitting the target.

The mechanism will be able to throw the ball to various distances. The position of the target will be changed in

the exam day and you will adjust the mechanism to achieve the goal.

ATTENTION!

Before you start to prepare your project, please

read the instructions carefully!

$1.$

Each group will consist of $5$ students. Group members should be specified at the beginning of the project

and will not change.

$2.$

Design details will be presented as a report! $($All the calculations, technical details, drawings, material

and equipment that you are going to use, production plan of your design should be included in the

report!$).$

Deadline of the report is January $7$

th

$.$

$3.$

At the date of evaluation $($

January $7$

th

$),$ the groups must present their designs. You should perform a $5$

min. presentation to show the design steps of your project including the calculations.

Every member

within the group must have a contribution to the presentation!

$4.$

During the demonstration, you should be able to adjust your system as below:

a$.$

You should be able to change your initial speed.

b$.$

You should be able to calculate and specify the position where the ball will fall into. You should

make to ball fly over the net and bounce one time $.$

c$.$

You should use a circular target are of $10$ cm diameter.

d$.$

Distance of the target will be given just before the demonstration. You should be able to adjust

your system according to given distance.

e$.$

You should show the calculations that you made to achieve the given task. Also, you will

calculate the coefficient of restitution of the impact between the ball and the ground.

f$.$

The height of the net is $20$ cm$.$

g$.$

Any type of ball can be used
