A steel rope has length L, area of crosssection A, Young’s modulus Y. [Density=d]
(a) It is pulled on a horizontal frictionless floor
with a constant horizontal force F = [dALg]/2
applied at one end. Find the strain at the
midpoint.
(b) If the steel rope is vertical and moving with
the force acting vertically upward at the upper,
end. Find the strain at a point L/3 from lower
end
