Q:

What is the mechanical advantage of an inclined plane?

A:

Quick Answer

The mechanical advantage of an inclined plane can be calculated by dividing the inclined plane's length by its height. The mechanical advantage of an inclined plane represents how less work is needed to move an object up a ramp compared to directly lifting it from the ground.

Full Answer

Inclined planes are often used when heavy objects need to be moved to a higher vertical position. Instead of lifting the object up, it can be pushed up a ramp. The ramp allows a lower amount of force to be spread out to accomplish the same task. This is because work is equal to force multiplied by distance. The work stays the same, the distance increases, so the force required is less.

  • Q:

    How does an inclined plane make work easier?

    A:

    An inclined plane makes work easier by reducing the exertion needed for the job while increasing the distance over which that exertion is maintained. The angle at which a load is lifted determines the amount of exertion needed to lift it. Lifting a load straight overhead requires the most exertion.

    What is the mechanical advantage of a wedge?

    A:

    The mechanical advantage of a single wedge is calculated by using the formula MA = length of slope/height of slope, where "MA" denotes the mechanical advantage. For a double wedge, the formula for solving the mechanical advantage is MA = effort distance/resistance force distance.

    What is an inclined plane wrapped around a cylinder?

    A:

    When an inclined plane, a type of simple machine, is wrapped around a cylinder, it forms a screw, which is another type of simple machine. Machines are mechanisms that can make work easier to do.

    What are seven simple machines?

    A:

    The seven simple machines are the inclined plane, wedge, screw, lever, pulley, gear and wheel and axis. The simple machines are non-powered mechanical devices that change the direction or magnitude of a force. Each of these machines is considered to be a simple machine. However, when combined, they are considered a complex machine.
