Concept explainers

Slope and Deflection

The slope in a deflected beam is described as an angle in radians made by the tangent of the section with the original axis of the beam. The deflection at any point on the axis of the beam is defined as the lateral displacement of the point before and after loading.

2) Orthogonal Cutting: Consider a person who is shoveling snow from the sidewalk. This person can choose between two different shovel designs. Shovel A rides at a 5°angle off the normal to the sidewalk, while shovel B is oriented at a 30° angle (from the normal to the sidewalk). Either way, two inches of snow will be removed. Which shovel will require less pushing force? Please write your answer as the ratio of the force for shovel A to the force for shovel B. Assume the friction between the snow and the shovel is 1.0. Both shovels are the same width (into the page). The thickness of the removed snow riding up the face of the shovel is as shown in the figures. In both cases, the snow has the same physical properties (strength, stiffness, etc.). 2 in snow 3 in ground Shovel A 5 degrees shovel Pushing force 2 in snow ground 30 degrees /2.75 in shovel Shovel B Pushing force
