Hi,

When the piston is at top dead center, it has been decelerating, pulling on the connecting rod, and the counterweight is exerting a force in the opposite direction. But what happens when the piston is at half-stroke?

Now, we have the counterweight exerting a shaking force at a right angle to the piston. The piston is not exerting any shaking force because, in mid-stroke, it’s moving at a constant speed, neither accelerating nor decelerating.

This is the problem of trying to balance an engine with rotating counterweights. Every time we add counterweight, we’re trading one form of imbalance for another. There is no way that a rotating counterweight can cancel a straight-line shaking force.


Please help.

Thanks!


I didn't find the right solution from the Internet.
