At a construction site a pallet of bricks is to be suspended by attaching a rope to it and connecting the other end to a couple of heavy crates on the roof of a building. The rope pulls horizontally on the lower crate, and the coefficient of satic friction between the lower crate an the roof is 0.666. The crates on the roof weigh 150lbs and it is on top of a 250 lb crate.What is the weight of the heaviest pallet of bricks that can be supported this way, and what is the friction forse on the upper crate under these conditions.STEP BY STEP PLEASE
Notify local factories that use pallets, that you have used pallets for $3.00 each. Blue pallets, that have the owners name on them, are worth a $15 deposit. Contact a tree removal company. They sometimes make mulch from the trees they cut down, and may use your pallets. Put a few near the road, with a sign Pallets for fire wood
