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, as shown in . The 150 lb rope pulls 250 lb Bricks horizontally on the lower crate, and the coefficient of static friction between the lower crate and the roof is 0.399. Part A What is the weight of the heaviest pallet of bricks that can be supported this way? (Hint: Start by drawing appropriate free-body diagrams.) Express your answer in pounds.
