This lecture is about Physics torque. I attach an image of the question. Please write detail to solve the solution. Solved the mobile problem. I would also like to see your work written (or typed) on paper as much as possible also like a detail.

Engineers find a new metal that is stronger than steel but much lighter. this material is also significantly cheaper than what is currently used for most aircraft, available in large quantities, and easy to manufacture. the engineers are excited because this new material will lower the costs of buying and operating airplanes for companies. what is probably the best step for the engineers to make next?
