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 B shovel Pushing force

a. What is the ideal mechanical advantage of this system? The inclined plane dimensions are 7.2 meters length and 1.8 meters height.b. What effort force is required to move the 600N create? c. In practice, you need to supply an effort force of 75 N to lift the crate. What is the efficiency?d. How could you redesign this compound machine so that the effort force needed was 50 N in practice? Assume the efficiency is your response from part C no matter what changes you make. Be specific with the changes you propose (if you add pulleys state how many, if you change the inclined plane dimensions state the new dimensions, etc.).

During shaft design, the locations with the minimum torque and moment should be identified. C. A rivet can always provide a much stronger attachment than a bolt or screw of the same diameter. D. Power screws are used to convert the rotary motion of either the nut or the screw to relatively slow linear motion of the mating member along the screw axis. E. Single-row ball bearings (as shown in the figure below) can carry a significant amount of trust load and can carry more trust load than roller bearings (as shown in the figure below). single-row ball bearing Explanation: roller bearing
