Under these circumstances, what maximum weight would you attempt to lift?

Question

Suppose you wanted to limit the force acting on your joint to a maximum value of 8.29 102 N.

(a) Under these circumstances, what maximum weight would you attempt to lift?Fmax =

(b) What force would your biceps apply while lifting this weight? Fbiceps =

Answer 1

need to know the mechanics of the lift you are proposing. Otherwise the answer is just 826 N.

Are you worrying about compresive load? Tensile Load? Which Joint?

Answer 2

When lifting something, I would suggest making that your joint is directly over the object. By doing so, you eliminate any chance of increasing stress on your joints if the weight is offset and the magnitude of the force is increased from a lever effect. Remember, your arm and other limbs act like levers. Lifting any weight with an out-stretched arm is far more stressful than lifting it from directly above.
