What is the resultant moment about point B? Express your answer as a Cartesian vector.

I need the solution in fifteen minutes please bro.

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

Write TRUE is the statement/s is True. If the statement is false, identify the word/s that makes the sentence incorrect and write its corresponding correct answer.  7. In planning, the tool travels along the workpiece during the removal of the material on the workpiece. 8. The factors that can be manipulated in cutting process are cutting speed, feed and depth of cut. 9.In thermally assisted machining, the tool is heated which reduces the required cutting force.
