1.If a concrete beam with a f'c=4000psi experiences a drop in temperature of 30 Degrees F, What is the internal tensile stress? Will the concrete crack? What could i do to prevent cracking?
2.In the context of JCT 2005, to what extent can a subcontractor negligently set fire to an existing building with impunity?
3.What is the difference between High-hazard H2 and H3 building occupancies and provide an example for each.
4.Describe how edge dislocations move under an applied axial stress on a single crystal cylindrical rod, with the primary slip system at 45deg to the axial direction. You may want to draw diagrams.
Could you explain this please?
