Problem 3: A small gearing system in your brand-new 3D printer fails as you were printing, leading to an overload in the motor and a fire in your home. The fire spreads, burning half of Everglades National Park in the worst environmental disaster in US history. The printer company blames you! Stating that you must have been misusing the printer some- how. Use your engineering knowledge to "show those jerks you mean business!" You investigate and find a serial number on the gears and type it into Google, finding the company that manufactures the gears. Their website provides some info that this series of gear is made from AISI 4340 steel and the yield strength is 125 kpsi. Assuming each gear tooth acts as a small cantilever, prove to the 3D printer company that they are liable for the fire. oct # Gear Information Gear radius (r): 1.00 in Tooth length (1): 0.15 in Tooth height (h): 0.15 in Tooth thickness (b): 0.1 in Angular velocity (w): 0.1 rad/s Motor Information Power (H): 0.009 hp 1…
Handwriting not allow please And give me complete answer
A machine makes two components; call them types A and B. It takes 250 seconds to switch production between the component types. During that time, no production occurs. When in production, each unit of A or B requires 0.5 second to be completed. The two components, A and B, are combined in an assembly process to make a final product; call it C. The assembly step can combine the two components into 1 unit every 2 seconds, or 30 units per minute. Assume there is ample demand. Suppose the machine rotates between one batch of 1,000 units of A and 1,000 units of B. What is the average inventory of B components? answer:______units
