The formula to calculate the Effort Required to Move Neglecting Friction is:
\[ P_0 = W \cdot \sin(\alpha_i) \]
Effort Required to Move Neglecting Friction is the force required to move the body up/down the plane neglecting friction. Weight of Body is the force acting on the object due to gravity. Angle of Inclination of Plane to Horizontal is formed by the inclination of one plane to another measured in degrees or radians.
Let's assume the following values:
Using the formula:
\[ P_0 = 120 \cdot \sin(0.40142572795862) = 46.8877354187045 \]
The Effort Required is 46.8877354187045 Newtons.
