To use the shear formula, the internal shear force must be:
Group of answer choices:
O vertical.
O horizontal.
O directed along an axis of symmetry of the cross-section.
O directed parallel to the edge of the cross-section.

vertical, and directed along an axis of symmetry of the cross-section

Explanation:

Shear is a force in an object is in the form of stress or strain. Shear strain is the ratio of length of deformation (extension) to the perpendicular length in the plane of the force applied. Shear stress, which is the stress that tends to shear a material,  is the ratio of shear force applied on a surface to the area of the surface.

The shear formula can be used to determine the maximum shear in an object and is given by; τ = . It is applicable when the internal shear force is vertical and directed along an axis of symmetry of the cross-section.

d would be the most obvious choice to this question. leaders are supposed to herd their underlings like a shepherd to sheep. a leader should also listen to others when they are talking to one other to gain a better understanding of their mission and surroundings.
