The press shown is used to emboss a small seal at E. Knowing that the vertical component of the force exerted on the seal must be 900 N, determine (a) the required vertical force P, (b) the corresponding reaction at A.
CHAPTER 6 Excavation, Grading, and compacted Fill 1. When we remove soil or rock, we make a cut or excavation 2. When we add soil or rock, we create a fill embankment 3. Virtually highways require earthwork to create smooth grades an alignments to provide proper surface drainage. 4. EARTHWORK is important especially in hilly areas. 6.1 Earthwork construction: 1. The fundamental objective of earthwork construction is to change the ground Surface from initial configuration to final configuration 2. These changes are necessary to maintain proper surface drainage 3. Earthwork must not create slope stability problems in hilly and mountainous areas In 1960: building codes began to include stricter req
