12. “The farther away, the less it should weight.” Express this in an equation of spinal torque, considering object and body weight.

arm strength is greatest at a reach distance of .5m or .75m?

At what distance above and below the surface of the earth a body will have same weight, (take radius of earth as

At what distance above and below the surface of the earth a body will have same weight, (take radius of earth as R.)5√R−R3√R−R2R25√R−R2

5. Where in the body do the NIOSH lifting guidelines minimize stress? 6. Is arm strength greatest at reach distance, .75 (reach distance), or .5 (reach distance) and why?

A pirate demands that his 75 kg prisoner “walk the plank”. The prisoner walks out on an 8.0 m long, 50 kg horizontal board that juts out from the side of the pirate ship. If he walks out and stands 7.5 m from the place where the board is connected to the ship’s side, what is the net torque applied to the board?
