Question

A light rigid bar AB is suspended horizontally from two vertical wires, one of steel and one of brass,as shown in figure. Each wire is 2.00 m long. The diameter of the steel wire is 0.60 mm and the lengthof the bar AB is 0.20 m. When a mass of 10 kg is suspended from the centre of AB bar remainshorizontalO What is the tension in each wire?Steel Brass(11) Calculate the extension of the steel wire and the energy stored in it.(ii) Calculate the diameter of the brass wire.(iv) If the brass wire were replaced by another brass wire of diameter 1 mm, where should the mass besuspended so that AB would remain horizontal? The Young modulus for steel = 2.0 x 1011 pathe Young modulus for brass = 1.0 x 10" Pa.​
