In the figure, a 128 kg uniform log hangs by two steel wires, A and B, both of radius 1.15 mm. Initially, wire A was 2.80 m long and 2.00 mm shorter than wire B. The log is now horizontal. Young's modulus for steel is 2.00 × 1011 N/m2.
What are the magnitudes of the forces on it from (a) wire A and (b) wire B? (c) What is the ratio dA/dB?
[tex]Force/Area = E (ΔL/L)[/tex]
L is length of wire
The Attempt at a Solution
edit. i managed to get the forces, working on da/db
