1. The problem statement, all variables and given/known data The Babblers have decided to build a tower that would reach the top of Rock Candy Mountain. For brick they used large sugar cubes ( = 1500 kg/m3). The compressive strength (stress) of sugar cubes is 6.0 MPa. How tall of a tower can the Babblers build? 2. Relevant equations Stress = F/A = Y(ΔL/L0)A 3. The attempt at a solution I converted 6MPa to N/m2 for 6,000,000 N/m2, I just don't know how to find L. The A's cancel, leaving me with F = Y(ΔL/L0), right? Is Y = 1500 kg/m^3?
