Thank you.. Got smthng new to think over.. But will it be applicable in case of ropes also or in low scale use!??

Take any case where there is a pulley and it is not fixed one though.. So will it affect the amount of force required to lift weight.. Because as much I know it's the tension that decides.. But jst I was wondering if diameter of the pulley used will also affect or not?

Whether the diameter/radius of pulley affects the force required in lifting a weight?
