A composite rod with a total length of 200 mm consists of a steel rod that is 140 mm long and 20 mm in diameter, which is rigidly attached to the end of a brass rod that is 100 mm long and 30 mm in diameter. The rod is used as a tie in a link mechanism and the strain in the brass rod is limited to 0.53 x 10-3. Given that the total extension of the composite rod must not exceed 0.1800 mm and E for the steel is 200 GPa, calculate the

 (a) strain in the steel rod; 

(b) load carried by the steel rod;

 (c) load carried by the brass rod; and 

(d) modulus of elasticity for the brass.
