fixed and movable pulleys can be combined.
Pulley reduces the force given to get the work done. There are amny types of pulleys. Examples are fixed pulley, movable pulley and Combined pulley.
A combined pulley system makes it easier to lift an object compared to a single pulley system. By distributing the load across multiple pulleys, the force required to lift the object is reduced.
make life easy to lift
One disadvantage of a combined pulley system is increased complexity, which can make it more difficult to set up and maintain compared to a simple pulley system. Additionally, the multiple pulleys in a combined system can introduce more points of potential failure.
A device used to lift something heavy. By using a pulley, you half the effective weight.
I don't actually know for sure
a few jobs are people that wash windows and painters
A combined pulley system can reduce the amount of force needed to lift a load, but it depends on the specific setup of the pulleys. In an ideal scenario, a combined pulley system could reduce the force required by half, but this is not always the case in practice due to factors such as friction and inefficiencies in the pulley system. Consulting a physics textbook or a professional engineer could provide more accurate information for a particular system.
Lifting something by artificial means like a pulley.
Two combined monosaccharides, (carbohydrates).
maybe or maybe not it may depend on what type of elevator it is but i think yes
it is the drive where the driver pulley is compressed by belt on slack side and with less friction on the driven pulley with opposite direction of motion.
