Common examples of simple machines include the hammer, crowbar, knife, log splitter, scissors, light switch, door knob, escalator, ladder, screwdriver, ramp, stairs, car jack, curtain cord and steering wheel. The six types of simple machines include the wheel and axle, inclined plane, simple lever, pulley, wedge and screw. The wheel and axle, simple lever and pulley constitute the lever family, while the inclined plane, wedge and screw are part of the inclined plane family.Continue Reading
A machine is an electrical or mechanical contraption that lightens a workload. It utilizes energy to alter the direction, increase the rate, transfer or multiply the force required to carry out a particular task. There are two types of mechanical machines: simple and compound. A simple machine is composed of only one mechanical apparatus, while a compound machine comprises two or more simple machines.
Simple machines provide a mechanical advantage, which is the factor by which a machine increases the magnitude of a force. The work output refers to the amount of work done by a machine, while the work input pertains to the amount of work exerted into the machine. The lever family exerts a rotational force that changes the direction of the work output from the work input. The inclined plane family alters the direction of work output at an angle of 90 degrees to the direction of the work input.Learn more about Physics
To remove a roof vent cap, you need a screwdriver, utility knife, extension ladder, cat's paw pry bar and a hammer. This is fairly easy to do, but you need to be careful since you need to access the roof to remove the roof vent cap.Full Answer >
Examples of compound pulleys include construction cranes, bodybuilding machines, block-and-tackle systems and some elevators. Each of these devices uses more than one pulley to change the direction and multiply the applied force.Full Answer >
Some examples of complex machines are cars, bicycles, can openers, a wheelbarrow, scissors and a stapler. A complex machine is also known as a compound machine, which consist of two or more simple machines, such as levers, wedges, pulleys, screws, wheel and axle and inclined planes.Full Answer >
Some examples of compound machines include scissors, wheelbarrows, lawn mowers and bicycles. Compound machines are just simple machines that work together.Full Answer >
