Q6. A simply-supported beam spans 10 m and is made from a 700WB150 steel section. A static vertical concentrated load of 400 KN is applied as shown in Figure. In the event of a fire, the temperature of the steel rises at a constant rate of 15 °C per minute up to a maximum of 750 °C. Assume that, at 20 °C, the steel has a yield stress of 300 MPa and Young's Modulus of 200 GPa. The ambient temperature (before the fire starts) is 20 °C. Determine whether the beam will collapse during the fire, and if so, how long after the start of fire will this occur? Self weight 400 KN

Measuring is the comparison of a particular physical quantity with its reference value. A unit is a fixed physical quantity. The length is a physical quantity. A physical quantity is the product of a unit and the numerical value we need to compare with.
