Yes, pulley is a simple machine.

∙ 11y agoTrue, a pulley is considered a simple machine. It is used to lift or move objects by changing the direction or magnitude of the force applied.
True. A screw is a simple machine that converts rotational motion into linear motion. It is typically used to hold objects together or lift loads.
False. A pulley system can change the direction of the force applied, but it does not always result in the output force being in the opposite direction of the input force. The direction of the output force depends on the configuration of the pulleys in the system.
False. Friction typically reduces the efficiency of a machine by converting some of the input energy into heat, rather than converting it into mechanical energy.
True. The mechanical advantage of a machine is determined by the ratio of output force to input force. A mechanical advantage greater than 1 indicates that the machine amplifies force, making it easier to do work.
False. Friction can significantly affect the efficiency of a machine by causing energy losses and reducing its overall performance. Minimizing friction through proper lubrication and design can help improve the efficiency of a machine.

I'd go with simple machines. Specifically, probably a pulley (or pulley system).
A computer is a man made device true or false
false.
False
No. A simple machine such as a lever could quite easily give a mechanical advantage of 10, 100 or more, or could even be less than 1.
True!A toboggan is a simple sled that originated in Canada.Read all about toboggan at:toboggan
False
no its a grooved wheel with a rope running along the groove the above answer is wrong because it is the definition of a pulley. Yes that is true. A wheel and axle is a simple machine consisting of two wheels of different sizes that rotate together.
True, if u teach them.
True.
