Dynamics problem... |
am scratching my head from some time about this problem..
Here it is ...
The saw blade in a lunber mill is required to remain in the horizontal
position and undergo a complete back and forth motion in 2 seconds. An
electric motor, having a shaft rotation of 50 rad/ sec is available to
power the saw and can be located anywhere. Design a mechanism that will
transfer he rotation of the motor's shaft to the saw blade. show
calculations of the kinematics of the saw blade. and include a plot of
the velocity and acceleration of the saw blade as a function of
horizontal position.
I was thinking may be I will use a crank and slider mechanism... but
then I was not sure of the calculations..

It might be worth looking up sawmills on the internet and see what type
of setup is commonly used.
Your setup will directly affect your calculations of course, so without
a good knowledge of how you have your mill set up, it will be hard to
provide much assistance. I *think* what you're referring to is similar
to a drive shaft (or whatever it's called) you see in a car, which
would probably work fine. Could you maybe give more details on your
proposed solution?
