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 The most massive flying dinosaur was the pterosaur.

Explanation / Answer

Qnet = m1*g*L/2 + m2*g*L = (80*9.8*0.5*L)+(120*9.8*L) = 1568 L

but Qnet = 9400

L = 5.99 m
