The assembly consists of two 10-mm diameter steel rods AB and BC, and a rigid bar B. After applying the loads shown, determine: (1) The maximum normal stress developed in each rod. (2) The horizontal displacement of end C with respect to the fixed support at A. (3) Suppose that only rod BC is exposed to change in temperature, what would be the change that keeps point C in the original position. Use Est = 200GPa, x= 12(10)-6 600 mm 400 mm 50 KN 40 kN 50 kN B C

Fire safety

Fire safety is a new domain emerged in the early 90s to enable the design of buildings, structures, and infrastructure against destruction through fire. It also includes the provisions of building codes. This field is mostly associated with the design and efficient planning of a building, to reduce the destruction caused by fire. The branch of engineering that deals with it for the safety of the buildings from destruction of fire, is known as fire safety engineering.
