I am looking for free pallets in Virgina...I cant find them any where please help me. thank you.
It sounds like the crates are stacked, the bottom weighing 250 lb, the other 150 lb. Then the normal force under the bottom crate is Fn = 400 lb, making the friction force Ff = ?Fn = 0.666 * 400lb = 266.4 lb. Therefore this is the heaviest pallet of bricks that can be supported in this way. I'm not sure I understant the last question, as far as under these conditions goes. As long as the pallet of bricks is in equilibrium, the friction force on the upper crate is zero.
Would that happen to be Donkey Kong? I'd fetch Mario, Luigi and Link to help me defeat him!
