Transcript of Simple machines
An inclined plane, lever, wheel and axle, and a pulley are all
simple machines. Pulley Definition: A simple machine made from a grooved wheel with a rope or chain wrapped around the grove.
This machine is helpful because a fixed pulley changes the direction of the input force, a movable pulley multiplies the input force. A wedge is a simple machine consisting of an inclined plane that moves. Can have two sloping sides.
Your front teeth are wedges and they can be used to tear apart an apple. A wedge increases the output force. A wedge is a simple machine consisting of an inclined plane that moves. Can have two sloping slides.
Your front teeth are wedges and they can be used to tear apart an apple. Wedge Lever A device made from a rigid that pivots or rotates on a fixed point. First and second class levers increase the output force. First class levers change the direction of the force. third class levers increase the distance of the output force Simple Machines A device that has only one movement.
A pulley, wedge, lever, screw, inclined plane, and the wheel and axle are all simple machines. Wedge Pulley A pulley is a device made from a grooved wheel with a rope or a chain wrapped around the groove. A moveable pulley makes work easier by increasing the output force. A fixed pulley changes the direction of the force. Lever A device made from a rigid bar that turns on a fixed point. First and second class both increase the output force. First class levers also change the direction of the force. Third class levers increase the distance of the output force Screw a screw is a device made from an inclined plane wrapped around a cylinder. A screw makes work easier by increasing the output force. Inclined Plane A device with a flat, sloped surface. The inclined plane makes work easier by increasing the output force. Wheel and Axle A device made from two different-sized,circular objects that are connected and rotate together. The wheel and axle makes work easier by increasing the output force. When you turn the wheel it turns the axle with a greater output http://conveyor-chains.net/wp-content/uploads/2011/01/pulley.jpg http://www.christopherconstructioncompany.com/sitebuildercontent/sitebuilderpictures/Barnwood/Pulley.jpg Bibliography http://frankandandyschleck.com/images/cervelo-S3-hi.jpg http://ed101.bu.edu/StudentDoc/current/ED101sp10/rawdons/images/wedge_rev.gif http://upload.wikimedia.org/wikipedia/commons/9/92/Scissors.png http://www.engquest.org.au/Images/Machines/SM_diagram12.jpg http://upload.wikimedia.org/wikipedia/commons/thumb/b/b1/Wood_screw_big.svg/184px-Wood_screw_big.svg.png http://www.photospin.com/content/photos/full/0480068.jpg http://www.allinallsports.com/products_picturehttp://www.photospin.com/content/photos/full/0480068.jpgs/traclarge.j http://0.tqn.com/d/homeschooling/1/0/7/Z/4/machinelever.png http://www.dimensionsguide.com/wp-content/uploads/2010/01/Wheelbarrow.jpg http://learn.uci.edu/media/OC08/11004/OC0811004_L6WheelAndAxle2.gif http://01.edu-cdn.com/files/89501_89600/89547/file_89547.jpg http://images1.fanpop.com/images/photos/1300000/2008-Obsidian-SG-One-Ford-Mustang-muscle-cars-1353007-1280-960.jpg http://msgirardsonlineclassroom.pbworks.com/f/1287334684/ramp.gif http://brainbits.per.sg/science_simple%20machines_inclined%20planes_pic_inclined-planes.gif http://www.richardperkinsarts.com/Waterslide07.jpg By: Travis Wysocki Great Sites http://www.edheads.org/activities/simple-machines/ http://www.mikids.com/Smachines.htm http://sln.fi.edu/qa97/spotlight3/spotlight3.html
