- A 2.50-m-long steel wire has a radius of 0.075 cm. How much tension is needed to stretch the wire 1.0 cm?A 13.2 kg child jumps up and grabs a (round) horizontal tree branch that has a diameter of 5 cm. The child grabs the branch 30 cm from the trunk, and the weight of the child causes the branch to sag. If the shear modulus for the tree is 1.016 x 10° N/m2, how how much does the branch sag when weighted? cmA cable used to lift heavy materials can resist breaking even under a load of 1 meganewtons. The steel cable must support twice that load for safety purposes. By how much the steel cable will stretch if it carries 1 meganewtons of load? Assume 8.0 m initial length of the cable. Group of answer choices 0.01 m 0.001 m 0.2 m 0.1 m 0.02 m 0.002 m
