The model represents the sliding-Tipping mechanism where the motion of the weight box is determined by the force applied to the box, weight of the box, dimensions of the box, reaction to the weight and coefficient of the friction.

 

The simulation model uses the equilibrium equations as follows:

SFx=FA-Wx-Fr=0

 

SFy= Wy-N=0

 

SM=Wx*x + Wy*h/2-FA*h=0

 

FA=Applied force                                                       Fr=Frictional force

 

Wx=Weight component along x-axis                        Wy=Weight component along y-axis 

 

h=Height of the block                                                 N=Reaction to the weight of the block

 

x= location along the x-axis where the “Reaction” (N) is acting.

 

The maximum frictional force is Fr=m*N where m is coefficient of friction.

Using the different sliders shown at the right side of screen following parameters can be changed:

Applied force

Box weight

Box width

Box height

Coefficient of friction

 

On checking the checkbox in front of Free Body Diagram the free body diagram can be viewed for that particular case depending on the values of the parameters described above.

 

The Test button on clicking starts the process of testing the system and shows the “reset” text on button that can be clicked to reset initial values.
