1. The length of a reading room in a library is 10 m and its breadth is 8 m. Compute the distributed live load, assuming the basic value of the load to be 2873 N/m2.

2.For thin-walled cylindrical tubes that are pressurized, the circumferential stress is a function of the pressure difference across the wall (?p), cylinder radius (r), and tube thickness (?x) as s=r?p/4?x. Compute the circumferential stress to which the walls of this pressurized cylinder are exposed.
