Dear Kavya Mani, This human body requires an average of around 280 days to form,how come you expect to learn its biomechanics within a day???? Regards Dr L Nivedita Selvakumar PT,CNMT(USA) Founder, Sri Aahana Physiotherapy Academy
How come when I search for whether the pulley larger in diameter requires less force to lift something the answer is no? I would think that the semi-diameter is a moment arm and thus the pulley larger in diameter would be more efficient. Any thoughts?
Dear Samo, Whenever the moment arm is more ,the force required to complete work will be less ,but when the moment arm is less you will have to apply more force.Moreover the mechanical advantage of both small size and large diameter pulleys will be same in the absence of friction.Hope it is clear now.

@@Physiocbe thanks for the answer Nivedita. So how come increased moment arm of the quadriceps thanks to patella increases the torque, but the simple rope pulley larger in diameter doesn't increase the torque?
@@samozeleznaterapia3643 diameter of the pulley doesn't matter but the number pulleys irrespective of the diameter is more important to complete work wid effort
@@Physiocbe but why the diameter doesn't matter? It does matter with anatomical pulley because it makes the moment arm of the muscle longer. If you would have one shoulder joint larger than the other one, the larger one would make the deltoid to work less, correct? I just cannot understand why we talk about moment arm with anatomical pulley, but it doesn't matter for simple rope pulley.
