Question: What is the angle of inclination at which the force of static friction equals the component of weight acting down the slope for a coefficient of static friction of 0.4?

Options:

21.8 degrees
22.5 degrees
23.5 degrees
24.0 degrees

Correct Answer: 21.8 degrees

Solution:

The angle θ can be found using tan(θ) = μs. Thus, θ = arctan(0.4) ≈ 21.8 degrees.

What is the angle of inclination at which the force of static friction equals the component of weight acting down the slope for a coefficient of static friction of 0.4?

Static Friction – The force that resists the initiation of sliding motion between two surfaces in contact.
Angle of Inclination – The angle at which an object begins to slide down a slope due to gravity.
Coefficient of Static Friction – A dimensionless value that represents the frictional force between two surfaces at rest relative to each other.
Trigonometric Functions – Mathematical functions related to the angles of triangles, used here to relate the angle of inclination to the coefficient of static friction.
