He discovered the principle of mechanical advantage in the lever. ]]> 2021-12-02 16:27:21 UTC https://padlet.com/alaniice/cgtb0dq7w3m3ohhr/wish/1925568546 alaniice https://padlet.com/alaniice/cgtb0dq7w3m3ohhr/wish/1925573979 A simple machine is a mechanical device that has a few moving and non-moving parts that make work easier by changing the direction of a force or by changing the amount of force needed. ]]> 2021-12-02 16:29:34 UTC https://padlet.com/alaniice/cgtb0dq7w3m3ohhr/wish/1925573979 alaniice https://padlet.com/alaniice/cgtb0dq7w3m3ohhr/wish/1925582311 About 2.6 million years ago the wedge was created by our ancestors Homo erectus, therefore this is the oldest simple machine. ]]> 2021-12-02 16:32:49 UTC https://padlet.com/alaniice/cgtb0dq7w3m3ohhr/wish/1925582311 alaniice https://padlet.com/alaniice/cgtb0dq7w3m3ohhr/wish/1925599417 The inclined plane, lever, wedge, wheel and axle, pulley, and screw. ]]> 2021-12-02 16:39:56 UTC https://padlet.com/alaniice/cgtb0dq7w3m3ohhr/wish/1925599417 alaniice https://padlet.com/alaniice/cgtb0dq7w3m3ohhr/wish/1925608745 A pulley helps lift things easier by changing the direction of force used to lift an object.]]> 2021-12-02 16:43:55 UTC https://padlet.com/alaniice/cgtb0dq7w3m3ohhr/wish/1925608745 alaniice https://padlet.com/alaniice/cgtb0dq7w3m3ohhr/wish/1925690112 By increasing the distance through which the force acts. ]]> 2021-12-02 17:19:03 UTC https://padlet.com/alaniice/cgtb0dq7w3m3ohhr/wish/1925690112 alaniice https://padlet.com/alaniice/cgtb0dq7w3m3ohhr/wish/1927288783 This simple machine helps remove the friction that is caused when moving objects and makes an easier movement. ]]> 2021-12-03 13:18:37 UTC https://padlet.com/alaniice/cgtb0dq7w3m3ohhr/wish/1927288783 alaniice https://padlet.com/alaniice/cgtb0dq7w3m3ohhr/wish/1927384808 Mechanical advantage is a measure of increased force achieved by using a tool. Meanwhile, mechanical efficiency is the measure of the effect that a mechanical system performs. ]]> 2021-12-03 14:02:49 UTC https://padlet.com/alaniice/cgtb0dq7w3m3ohhr/wish/1927384808 alaniice https://padlet.com/alaniice/cgtb0dq7w3m3ohhr/wish/1927982196 The input force is the amount of force or effort that we use in a simple machine to make it complete a task and the output force is the force used on an object by a simple machine.]]> 2021-12-03 18:53:23 UTC https://padlet.com/alaniice/cgtb0dq7w3m3ohhr/wish/1927982196 alaniice https://padlet.com/alaniice/cgtb0dq7w3m3ohhr/wish/1928303388 Door wedges, wheelbarrows, bicycles, garage doors, knives, see-saws, scissors, and more.]]> 2021-12-04 00:45:19 UTC https://padlet.com/alaniice/cgtb0dq7w3m3ohhr/wish/1928303388 alaniice https://padlet.com/alaniice/cgtb0dq7w3m3ohhr/wish/1928306862 Simple machines are important in our life because without them tasks will be much harder and will require more work. Also if simple machines weren’t created until now our society will be more will be in decline as it will be harder to complete tasks or simple tasks. ]]> 2021-12-04 00:50:31 UTC https://padlet.com/alaniice/cgtb0dq7w3m3ohhr/wish/1928306862
