Problem 6-133

The composite beam is made of A-36 steel (A) bonded to C83400 red brass (B) and has the cross section shown. If the allowable bending stress for the steel is (sallow)st = 180 MPa and for the brass (sallow)br = 60 MPa, determine the maximum moment M that can be applied to the beam.

Step-by-Step Solution:

Problem 6-133The composite beam is made of A-36 steel (A) bonded to C83400 red brass (B) and has thecross section shown. If the allowable bending stress for the steel is ( ) = 180 MPa and for allowstthe brass ( ) = 60 MPa, determine the maximum moment M that can be applied to the allow brbeam. Step-by-step solution Step 1 of 7 ^Obtain the following properties using Table “Average Mechanical Properties of TypicalEngineering Materials-SI Units”, from back side of the text book.Young’s modulus of A-36 steel, E = 200 staYoung’s modulus of C83400 red brass E br = 101 GPaTransform the whole section into one made entirely of brass.Calculate the transform factor. E st n = EbrSubstitute 200 GPa for E st and 101 GPa for E br. n = 200 GPa 101 GPa = 1.98 2\n
