The wires AB and BC have original lengths of 2ft and 3ft. When the load shown is put in place, it is known that wire AB
experiences a normal strain equal to 0.7% whereas wire BC experiences a normal strain equal to 0.3%. Given this information,
find the vertical and horizontal displacement of point B.
Hint: make sure to download the solution
slides. Use the displacement diagram
from the similar problem solved in this
video to express the square of the final
lengths of cables AB and BC in terms of
the unknown displacements Delta x and Delta y.
Expand the squares and neglect
quadratic terms Delta x^(2) and Delta y^(2). This will
result in a linear system of equations in
Delta x and Delta y. Solve it to obtain the answer.
