What is the power dissipated in the resistor that is dissipating the most power? R1=3.0Ω
R2=5.0Ω
R3=7.0Ω
Voltages=8.0V
R1 and R2 connected in parallel and R3 connent in series with battery

Asolid round steel rod 6.25 mm in diameter and 375 mm long is rigidly bonded to the end of solid square brass rod 25 mm on a side and 300 mm long. the geometric axes of the bare are along the same line. an axial tensile force of 5.4 kn is applied at the extreme ends of the assembly. for steel e = 200 gpa and for brass e = 90 gpa. determine the total elongation for the assembly.
