Consider a cube-shaped object. to shear it, equal but oppositely directed forces might be applied:
to opposite faces, perpendicular to the faces
to adjacent faces, perpendicular to the faces
to a single face, in any direction (you don't need two only one is required for shear)
to opposite faces, parallel to the faces
to adjacent faces, as long as the force is not perpendicular or parallel to the faces

A33.1 g copper object is launched from a 1.5 m 30° steel incline positioned on the floor by being pulled up a string attached to a 50.0 g mass suspended vertically over a pulley. the object is projected towards a glass table where it lands when it is at the point along its trajectory with the lowest speed. it comes to a halt when it clears the opposite edge of the table. it then falls and lands on 9 physics texts each 5 cm thick that are stacked on the floor on the opposite side of the table. assume that the table does not have a ledge and the rectangular object experiences 0.05 n of air resistance as it falls towards the books. how far and how long did the object travel and how fast does it hit the books. assume that at the moment the copper object leaves the incline, the massless string and ideal pulley break off

When the force acting on an object points at least partially in the direction of the motion the work done is considered to be negative
