Simple Machines Concept Review

A simple machine that consists of a sloping surface connecting a lower elevation to a higher elevation.

• Lever

• Inclined plane

• Pulley

• Wedge

The mechanical advantage of an inclined plane is always ________________________, because the machine puts out more Force than the user puts into it.

• greater than 1

• equal to 1

• less than 1

• between 0 and 1

Less Force is needed to move an object uphill with an inclined plane, but the force must be applied over __________________________.

• a smaller distance

• an equal distance

• a greater distance

• an equidistant force

Used to move objects to higher elevations more easily.

• Wedge

• Lever

• Wheel and Axle

• Inclined Plane

How do you calculate the ideal mechanical advantage of an inclined plane?

• Length divided by height

• Length times height

• Height divided by length

• Height times length

A simple machine consisting of two inclined planes giving it a thin end and thick end.

• Screw

• Pulley

• Wheel and Axle

• Wedge

Used to cut or split objects

• Screw

• Wedge

• Pulley

• Wheel and Axle

How does a wedge change the force applied to it?

• Force is applied to the thick end, and the wedge, in turn, applies force to the object along both sloping sides.

• Force is applied to the sloping sides, and the wedge, in turn, applies force to the object along the thick end.

• Force is applied to the handle, and the wedge, in turn, applies force to the object along the handle.

• Force is applied to the end of the rope, and the wedge, in turn, applies force to the output end.

How do you calculate the actual mechanical advantage for all simple machines?

• Output Force divided by Input Force

• Input Force times Output Force

• Output distance times Input distance

• Input Force divided by Output Force

How do you calculate the ideal mechanical advantage of a wedge?

• Depth of wedge times the separation of wedged surfaces.

• Depth of wedge times length of wedge.

• Separation of wedged surfaces divided by the depth of wedge

• Depth of wedge divided by the separation of wedged surfaces
