Answer:
0.00116
Explanation
The tensile modulus is the measure of the elastic deformation that a material has undergo.
While elastic strain is define as form of strain in which a body return to its original length after the removal of the force .
Strain s expressed as
Where e is the strain, A is the area, F is the applied force and E itensile modulus
From the data given,
Force, F=40,000
Area=πr^2
and the tensile modulus E=110GPa
If we insert values we arrive at
Hence the strain experienced by the material is 0.00116
You have to show the story or experiment so we know

Answer:
When a pilot pushes the top of the right pedal, it activates the brakes on the right main wheel/wheels, and when the pilot pushes the top of the left rudder pedal, it activates the brake on the left main wheel/wheels. The brakes work in a rather simple way: they convert the kinetic energy of motion into heat energy.
