Answer:
You can increase the ideal mechanical advantage of an inclined plane by decreasing the angle of the inclined plane
Explanation:
Mechanical Advantage Of An Inclined Plane
Since the sloping surface of the inclined plane is always greater than its height, the ideal mechanical advantage of an inclined plane is always greater than 1. To compute the ideal mechanical advantage for an inclined plane, we divide the length of the incline by the height of the incline. For example, An inclined plane that is 10 meters long and 5 meters high has an ideal mechanical advantage of 2.
If we look at the inclined plane as a triangle formed with the height and the horizontal surface, the length L of the inclined plane is the hypotenuse of such triangle and h is the opposite leg of the angle formed with the floor. Since:
[tex]\displaystyle sin\alpha=\frac{h}{L}[/tex]
The mechanical advantage is
[tex]\displaystyle MA=\frac{L}{h}=\frac{1}{sin\alpha}[/tex]
As [tex]\alpha[/tex] decreases, its sine also decreases and the mechanical advantage (its reciprocal) will increase. Thus the answer is
You can increase the ideal mechanical advantage of an inclined plane by decreasing the angle of the inclined plane
You can increase the ideal mechanical advantage of an inclined plane by
decreasing the angle of the inclined plane.
This is a term which is used to depict the ease at which work is done in
relation to the force applied.
A higher angle means that the frictional force is usually higher which
makes more force to be applied and work harder. Decreasing the angle of
the plane makes the frictional force lesser with a smaller force needed.
