Answer to Question #114966 in Mechanics | Relativity for howard

Question

See the picture on the board. In 1943, there was a gorilla named N’gagi at the San Diego Zoo; its mass was 310 kg. If N’gagi were to hang from a bar as shown, what torque would the gorilla exert about point A? Assume the bar has negligible mass.

Answer 1

Torque = $Distance \ from\ hinge\times weight \\=7\times mg=7\times310\times 9.8=21266\ N–m$
