The length of the spring, which was acted upon with a force of 5N, is 50 cm. Determine the length of the undeformed spring if the stiffness coefficient is 15 N / m.
Given: F = 5H, l1 = 50 cm, k = 15 H / m.
l0 -?
SI: l1 = 0.5m
Solution: k = F / change l => change (triangle, delta) l = F / k change l = 5/15 = 0.33 m = 33 cm => l0 = l1-change l = 50-33 = 17cm.
Answer: l0 = 17 cm.
