To make 5 aluminum wheels with smooth surface and precise dimension as shown in Figure 1 for one time order, what manufacturing processes would you suggest for the part. a)Sand casting, which has much lower initial tooling cost than die casting b)Machining processes from the 4 inch diameter round aluminum rods in stock. cut the rod into one inch long pieces with bandsaws drill the 0.88 inch diameter center hole on a lathe bore the 3.5 inch diameter inside blind hole on the same lathe drill the three 0.5 inch diameter holes on a milling machine or a drill press c)forging process with rounded edges and corners d)die casting, which can make the part in high production rate with smooth surface and precise dimension
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
Thank you for the professional solution, it is clear and makes a lot of sense. However, I thought block B was open-ended. Meaning A would slide through it. Let me know if I have misinterpreted the question.

Gentlemen, please help to solve a,b,c as I faced confusing questions about screw jack. Conditions are: screw jack is lifting 3.2 tonnes, screw pitch is 12 mm, diameter of the screw is 5 mm. Coefficient of friction was not given but I think we will need it for total force calculation, lets take it 0.2. a) Calculate horizontal component to move the load - what is ment here by horizontal component? b) Calculate vertical component to move the load - what is ment here by vertical component? c) Total force needed to move the load with a lever of 0.82m d) Velocity ratio (VR=distance by effort/distance by load) Distance by effort (lever)=2 x 3.14 x 0.82 = 5.15m Distance by load = pitch= 12mm= 0.012 m VR=5.15/0.012= approx 429. e) Calculate efficiency. For this we need to have MA (mechanical advantage). It can be calculated when we know total force. Efficiency=Load (3200 x 9.8) / effort
Calculate the tolerance if the maximum limit is 97.45 mm and the minimum limit is 96.99 mm.
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.).
Calculate the maximum limit if the tolerance is 0.004 cm and the minimum limit is 0.985 cm.
