it is due to the fact that the length of an inclined plane(effect arm) is greater than its vertical height(load arm).
No, if the mirror is flat (a plane), the angle of incidence always equals the angle of reflection.
Since the hypotenuse (denominator) is always greater than the opposite or adjacent side (numerator), the ratio will always be smaller than one.
An inclined plane is a flat surface that is tilted at an angle to the horizontal, allowing objects to be raised or lowered with less effort than lifting them vertically. It is a simple machine that converts the force of gravity acting on an object into a downward force along the slope, making it easier to move heavy items. Common examples include ramps, slides, and hills. Inclined planes are widely used in various applications, from construction to transportation.
They mean that the expression to the left of the sign is greater than or less than (as appropriate) the expression to the right of the sign.
Acute angles are greater than 0 but less than 90 degrees Obtuse angles are greater than 90 but less than 180 degrees Reflex angles are greater than 180 degrees but less than 360 degrees
When using an inclined plane, the effort distance (de) is greater than the resistance distance (dr). This is because the inclined plane allows you to apply an input force over a longer distance (de) to move a load up the inclined surface, making it easier to overcome the resistance force.
The mechanical advantage of an inclined plane is the ratio of the length of the inclined plane to the height it lifts a load. Since the length is always greater than the height (unless the inclined plane is vertical), the mechanical advantage is always at least 1.
DE is greater than DR
De is the length of the plane. Dr is the height of the plane. So it is impossible to make the length of the plane smaller than the height of the plane. This is why De is always greater than Dr.
Of course the length is greater than the height. Take the example of a right angled triangle where the hypotenuse is always greater than the other two arms.
DE is greater than DR
DE is greater than DR
de is greater than dr
No, a simple inclined plane always has a mechanical advantage of greater than or equal to 1. It reduces the force needed to lift an object by increasing the distance over which the force is applied. The mechanical advantage is calculated by dividing the length of the inclined plane by the height.
The mechanical advantage of an inclined plane can never be less than one because it is defined as the ratio of the length of the incline to the vertical height it spans. Since inclines always extend over a longer distance along the slope than they do vertically, the ratio will always be equal to or greater than one.
In an inclined plane, the mechanical advantage (MA) is always less than 1 because the input force needed to lift an object is greater than the output force. This is due to the trade-off between the distance over which the force is applied (input distance) and the vertical distance the object is lifted (output distance). The ideal mechanical advantage (IMA) assumes a frictionless system and is calculated based on the ratio of input distance to output distance, resulting in a value always greater than the AMA.
inclined plane makes life easier according to the length of the inclined plane.if we use a longer inclined plane,we will use less effort but the distace moved by the effort is greater than the load.but if we use a shorter inclined plane,we need to use more effort but the distance moved by the effort is less than the load.
