Question
A uniform bar AB of weight W 5 25 N is
supported by two springs, as shown in the figure. The
spring on the left has a stiffness k1 5 300 N/m and nat-
ural length L1 5 250 mm. The corresponding quanti-
ties for the spring on the right are k2 5 400 N/m and
L2 5 200 mm. The distance between the springs is
L 5 350 mm, and the spring on the right is suspended
from a support that is a distance h 5 80 mm below the
point of support for the spring on the left. Neglect the
weight of the springs.
(a) At what distance x from the left-hand spring (fig-
ure part a) should a load P 5 18 N be placed in
order to bring the bar to a horizontal position?
