Solve the given question:
Question: The most massive flying dinosaur was the pterosaur. The average mass for a pterosaur has been estimated from skeletons to be between 80.0 kg and 120.0 kg. The wingspan of a pterosaur was greater than 10.0 m. Suppose two pterosaurs with masses of 80.0 kg and 120.0 kg sit on the middle and the far end, respectively, of a light horizontal tree branch. The pterosaurs exert a net counterclockwise torque of 9.4 kN•m about the end of the branch that is attached to the tree.
Question 1: What is the length of the branch?
Please show all work and steps and equations to determine the length of the branch.
