A 300-pound load deflects a linear-rate coil spring 1 inch. A 600-pound load will deflect the same spring how much in total?
A) 1 inch
B) 2 inches
C) 3 inches
D) 4 inches

Question

Quizplus · Accepted Answer

The deflection of a linear-rate coil spring is proportional to the load applied. We can set up a proportion to determine the deflection for a 600-pound load:

300 pounds / 1 inch = 600 pounds / x inches

Cross-multiplying, we get:

300x = 600
x = 2 inches

Therefore, a 600-pound load will deflect the same spring 2 inches in total.
