there is three things that could have part of the stick may be jamed in the mower still, you may have bent the blade, or you may have bent the shaft the blade mounts to
Good thoughts but this is definitely it...
You sheared the shear pin and now the timing is off. The flywheel on top has a little slot in it where it connects to the motor shaft, to line it up for the timing of the engine.
There is a key way, most of the time it is aluminum. This is done on purpose so that if you run over something that stops the engine, it will shear the pin and stop the motor instead of damaging the actual engine.
The pin only costs a couple of dollars, but you need to remove the crank and get a puller to pull the flywheel off to replace the cheap little key way.
Go to a home repair center or a lawn mower repair center and get a package of key ways for your engine for starters. There are only a few types, depending on if your engine is Briggs and Stratton, or Tecumseh.
Hook up jumper cables to a different battery, stick the black cord on the frame of the mower to ground it; touch the red to the starter bolt and hold it there until it starts.
If the stick is just sitting there, it doesn't exert any force at all. If you're swinging the stick, the shape of the stick won't matter much; the force will be determined by the speed and mass of the stick. If you are poking with the stick, then the FORCE will be the same whether it is blunt or pointed - but a pointed stick will concentrate the force into a smaller AREA, so the force per area will be a lot higher with a sharp stick than with a blunt one.
There are quite a few things that a magnet can stick to. A magnet can stick to other magnets and certain metals.
There is an oil cap that usually has a dip stick attached
A memory stick is electric that holds lots of memory and thing from your computer
Sometimes Evelyn's lawn mower does this too. I take a sledgehammer and break it.
that depends on the force exerted by the stick on the puck. they are directly related, in other words F(puck to stick)=F(stick to puck)
All electric motors use magnetic force. So do electrical sound amplification systems. Magnetic levitation of high-speed trains is another example.
Electrostatic force
less tyan a qt, fill it almost to the top of the little hole, if theres NO dip stick, if you have a dip stick fill to the level on stick,
depending on what type of mower and who makes the motor it can vary. if it is a standard push mower you can either remove the dip stick/oil fill and dump the oil out there or look at the base of the motor for a plug or under the deck with the blade for a plug. if it is a riding mower there will be a plug at the base of the motor that can be removed to drain it
