How much force does an apple tree exert on an apple?

How much force is exerted on an apple of mass 421g by the branch holding it in place? If the tree holds 437 of these apples, whats the force required by the trunk to hold up all the apples if the branches holding the apples weight 84.1kg? Assuming the tree could support not even 1 more apple, what is the maximum amount of force that could be applied without risking its destruction, if the trunk of this apple tree was used as a ram in a penguin squashing factory?

Update:

Well the penguins I had in mind are rather small. Around the size that makes them not too difficult to put between the uprights. I also realize the tree could withstand a lot more mass, I just dont want to have to cut down another apple tree in order to get rid of these rodents. They've attempted a mutiny, but I've managed to take a few hostage and restore order. But I've also got to put a few down to reestablish some respect.

    each apple weighs 4.21N

    total weight of apples is 1,840N

    weight of branches is 841N

    total force on the trunk is 2,681N

    And if that was the maximum force the trunk could take, that would be the maximum force you could use it as a battering ram for.

    Btw, that is a very small force for a tree trunk.

    Dont forget the gravitation force the tree has on the apple lol.

    King Penguin or Emperor Penguin?

    Just apply Newton's law. The force required to hold one or more apples is idenicle to its/their weight, mg.

    when it attached to the tree, exactly equal to itsweight
