Question:

Problems 50–59 are based on material learned earlier in the course. The purpose of these problems is to keep the material fresh in your mind so that you are better prepared for the final exam. 

The strain on a solid object varies directly with the external tension force acting on the solid and inversely with the cross-sectional area. If a certain steel rod has a strain of 150 when the force is 1.47 × 104 N and the cross-sectional area is 4.9 × 10-4 m2 , find the strain for a similar rod with a cross-sectional area of 8.75 × 10-3 m2 and a tension force of 2.45 × 105 N.
