SUMMARY
The torque exerted by a 60 kg person on a diving board about the front support post (B) is calculated using the formula τ = Fr, where F is the force due to gravity. The correct distance from the support post is 3.0 m, leading to a torque of approximately 1800 N·m. The initial confusion arose from using an incorrect distance of 4.0 m, which pertains to a different point of reference (A). The calculation confirms that the torque about point B is indeed 1800 N·m in the counterclockwise direction.
