A spring stretches 5.0 cm when a 0.20 kg block is hung from it. If a 0.70 kg block replaces the 0.20 kg block, how far does the spring stretch?
we analyzed a cable used to support an actor as he swings onto the stage. Now suppose the tension in the cable is 940 N as the actor reaches the lowest point. What diameter should a 10-m-long steel cable have if we do not want it to stretch more than 0.50 cm under these conditions?
If it takes 5.30 N to stretch a spring 7 cm, and if the spring is then cut in 9 equal pieces, what force (in N) does it take to stretch one of the pieces 7 cm?

When Bob pulls on the right end with a 200N force, he stretches the spring by 20 cm. The same spring is then used for a tug of war between Bob and Carlos.

Since we apply a force in a horizontal direction, the spring is stretched to 28 cm. Now we suspend the spring from a hook in a vertical direction and attached a 15 kg mass at the bottom.

This ligament is much more elastic than a typical ligament, stretching from 15% to 45% longer than its resting length as a horse’s head moves up and down while it runs. This stretch of the ligament stores energy, making locomotion more efficient. Measurements on a segment of ligament show a linear stress-versusstrain relationship until the stress approaches 0.80. Smoothed data for the stretch are shown. Suppose the ligament has a circular cross section. For a certain ligament, an investigator measures the restoring force at a strain of 0.40. If the ligament is replaced with one that has twice the diameter, by what factor does the restoring force increase?A. 1.4B. 2C. 4D. 8arrow_forward
