Projek Reka Bentuk Teknologi / Sains Sekolah RendahReka Bentuk Mekanikal Sistem Takal ( Pully )Pulley is a simple mechanical device used to lift heavyobjects and save effort. Pulleys are divided into fixed pulley and movingpulley. The central shaft of the fixed pulley is fixed, and the central shaftof the moving pulley can be moved. Using fixed pulley does not save effort ordistance, but it can change the direction of applying force. Using a movablepulley can save half the force, but it costs half the distance and cannotchange the direction of applying the force. The fixed pulley and the movablepulley are combined to form pulley set, which not only saves effort but alsochanges the direction of applying force.#RekaBentukTeknologi#RekaBentukMekanikal#SistemTakal#STEM
