1  Newton / General / Re: Fix joint and push button on: October 08, 2010, 06:36:23 AM
This post was also answered in the technical support section. here is the answer:

In the attachment you can find a solution. I did the following:
1. put a temporary ball into the position of the "pushbutton_slider", and linked to the slider. in the material page uncheck "collision".

for a better view set the transparency to half opaque of the "pushbutton_base". now if you click on the push button, you can see, that the "pushbutton_top" and the temporary ball will move.

2. connect the 'green brick" the temporary ball, and the pushbuton_base into a fix joint.

3. also added a hinge joint, which rotates the brick.

This question was answered in the Technical support section, however I forgot to post it here.
so here is the solution. In the attachment there's an example too.

1. place a motor, and a gear
2. connect the gear and the motor,

3. The motor has a "hinge" called "motorm_shaft" the problem was that
by default  only one of the links are connected to the axel, the other
one isn't connected to the motor chasing. so on the properties window
of the hinge connect the "Link 1" to "motorm_chasing".

4. put down the brick, resize
5. put down a "hinge", and reposition it to the coordinates of the
brick, ( the x, y should be the same )
6. change the "hinge" axis of revolution to 0, 0, 1 , and connect it
to the brick.
7. in the same properties window, set the hinge velocity to example
20deg/sec and give some torque, ezample 10Nm

8. put down a battery, and a fixjoint, and fix the motor chasing,
motor stand, brick, battery.

9 connect the wires,

Save the experiment.

Can you provide us more information about the crash? I tried to make a
similar experiment shown in the attached picture, but I could not reproduce.

Note that now the Student version is available for EUR 49 only with
money back guaranty in case you are not satisfied. With this version you
can save your projects and send us in case you have problems.

You don't need to do anything special, just press enter when you want to start a new line.
If you want to calculate something more difficult, you can write small scripts.
There's an example in the file Freefall.ex:
  z0 : real;
  a : real;
  z0 := 2;
  a := 9.81;
  result := z0-0.5*a*time^2;
and additional information in the manual:

Hello Gaborba,

Yes, we designed newton to use it in the classroom also.
When you simulate a freefall, you can draw the trajectory of the falling body, and the theoretical curve on the same diagram.

For an example check out the Examples in manual\Freefall.ex file.
