Determine the location of the neutral axis and the design moment capacity, φmn, of the beam given below assuming that concrete with compressive strength of 6 ksi and grade 60 steel bars are used. in your calculation, consider the contribution of each layer of reinforcement based on its strain. the beam has a width of 20" and top and bottom cover of 2.5"

Iwill give brainliest if you answer right : )

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.

When is a current produced? when the terminals of an electrochemical cell are connected by a wire if the electric circuit is opened in an electrochemical cell if the electrolyte is removed from an electrochemical cell when the electrodes are reversed in an electrochemical cell
