USA HISTORY

Detailed explanation-1: -inclined plane, simple machine consisting of a sloping surface, used for raising heavy bodies. The force required to move an object up the incline is less than the weight being raised, discounting friction. The steeper the slope, or incline, the more nearly the required force approaches the actual weight.

Detailed explanation-2: -For a given height, as the steepness of the slope increases, the required length of the inclined plane decreases. However, when the steepness of the slope is more, it is more difficult to roll up an object over it.

Detailed explanation-3: -An inclined plane, also known as a ramp, is a flat supporting surface tilted at an angle from the vertical direction, with one end higher than the other, used as an aid for raising or lowering a load. The inclined plane is one of the six classical simple machines defined by Renaissance scientists.

Detailed explanation-4: -Slope refers to the angle, or grade, of an incline. Slope can be upward or downward. Slope is typically expressed as a percent, and corresponds to the amount of rise, or vertical distance, divided by the run, or horizontal distance. Percentage means per 100.

Detailed explanation-5: -Inclined plane is a slanting wooden plank or a sloping surface. It is a simple machine which is used to move a load up with less effort. The mechanical advantage of an inclined plane depends upon its slope and height.
