Comment on Diagram of a pulley system, demonstrating how pulleys facilitate the lifting of heavy weights (2004)

Nope. Right now the system is balanced, the rope is not being pulled just hold. To pull the weight up you need more than 50N, plus a bit more if we take into consideration the friction in the pulleys and in the rope itself.
