Question

this image shows the various forces acting on a block of rock situated on a rock slope. what does arrow 4 represent? a) shear strength b) normal force c) gravitational force d) shear force question 2 (5 points)

Explanation:

Shear force acts parallel to the surface of the slope. The normal force is perpendicular to the surface of the slope. Gravitational force acts vertically downwards. Shear strength is a property related to the material's resistance to shear - not a force shown in the basic force - diagram. Arrow 4 is parallel to the slope surface, representing shear force.

Answer:

D. Shear force
