In the case of the threads of a screw that we use in the fastening of the two pieces of wood that are found to have an angle, there is an increase in the value of the static friction force when we decrease the coefficient of static friction that exists between the screw and the wood. Option D.
The term static friction would defined as the kind of friction that is preventing two bodies that we know are in contact from being able to slide over each other. The angle at which the two objects have been inclined has a lot to do with the value of the coefficient of static fraction that exists between the objects
We could obtain the static fraction by the use of the formula:
F = μR
where
F = static frictional force
μ = coefficient of static friction
R = normal reaction
Thus, the static frictional force would be more or would increase if we decrease the coefficient of static friction.

Missing parts;
The threads of a screw used to fasten two pieces of wood are pitched at an angle. How does this increase the static friction force?(1 point)
Responses
A By decreasing the surface area between the screw surface and the wood
B By increasing the ease of inserting the screw into the wood
C By increasing the normal force exerted by the wood on the screw thread
D By decreasing the coefficient of static friction between the screw and the wood
