Give an example of an engineering application requiring high

Solution

crane hook is the best exxample for the high material toughness. Because the hook hold a high amount of load to carry from one place to another place. Which needs high strength to hold as much as load for the travel time and has undergones strained due to the static load . So the hook shoul have the capability of storing the energy with in it. for longer time. S,the hook is designed to store as much energy. this energy is the strain energy we can observe the by drawing the tensile test the area under the curve is the strain energy stored up to fracture.
