A particle has an initial speed of 27m/s. If it experiences a deceleration of (-6t)m/s^2, where t is in seconds, determine its velocity after it has traveled 10 meters. How much time does this take?
Determine the Modulus of Elasticity of Concrete by the ACI formula for a concrete cylinder that has a unit weight of 120pcf (1920kg/m^3) and a compressive strength of 3000 psi (21MPa).
How many floors can be added to the building while maintaining the code required overturning factor of safety of 2.0 Assume the roof supports a wind load of 4 kips and all floors below support a wind load of 8 kips.
Given the EPA acceptable risk level of 1 cancer in a million, what is the maximum concentration of TCE you can tolerate at the dry cleaning facility and keep your incremental cancer risk below the acceptable risk
As a civil engineer you look up in your strength of materials book and find out that the deflection, for a square beam of width, t, and length, L, when subjected to a tensile force, F, is given by: h=FL/(Et2), where E is Young's modulus.
