please answer correctly

B. The three bars supported a concrete
beam weighing 50 kN. The length of
steel is 0.50 m. Based on the given table
of the properties of the materials. both
materials have a temperature of 20°C.
When the beam is placed, the steel and
bronze bar temperature is 30°C.
Determine the length of the bronze bar
so that the load on each steel bar is
twice the load on the bronze bar and If
the length of the bronze bar will make
the steel stress twice the bronze stress
