One end of a stiff spring is attached firmly to the ceiling of a workshop (see figure). The load F (in pounds) required to stretch the spring by x inches is given by F = kx, where k is the stiffness constant Of the spring. a. Solve F = kx for x.
b. How far will the spring stretch if its stiffness constant is 5 lb/in and it is loaded with a weight of 25.5 lb? Round to the nearest tenth of an inch.
A) a. $x = \frac { F } { k }$ b. $5.1$ in.
B) а. $x = \frac { k } { F }$ b. $0.2$ in.
C) a. $x = k F$ b. $127.5 \mathrm { in }$.
D) a. $x = F - k$ b. $20.4 \mathrm { in }$.
