Theory of Structures A load of 1960 N is raised at the end of a steel wire. The minimum diameter of the wire so that stress in the wire does not exceed 100 N/mm² is: 5.5 mm 4.0 mm 4.5 mm 5.0 mm 5.5 mm 4.0 mm 4.5 mm 5.0 mm ANSWER DOWNLOAD EXAMIANS APP
Theory of Structures If Q is load factor, S is shape factor and F is factor of safety in elastic design, the following: Q = S – F Q = F – S Q = S × F Q = S + F Q = S – F Q = F – S Q = S × F Q = S + F ANSWER DOWNLOAD EXAMIANS APP
