A 20 degree-pressure-angle, 22-tooth spur gear has a diametral pitch equal to 5. Calculate the dedendum in mm

1) Prof. K. climbed a wall and is now stuck and hungry. One of her ME 242 students saw this opportunity to test one of their pulley mechanisms to lift some pizza boxes for Prof. K. If the student is pulling the free end with a velocity of 2.75 ft/s. a) What is the mechanical advantage between the student and the pizza boxes? Hint: The link between pulleys 1 and 4 is rigid (meaning that they must move together. This is the key to solving this problem! b) What is the velocity of the pizza boxes? Be sure to indicate which direction it is moving. [Ans. to check: 1.375 ft/s] PizzA 49°F Sunny O 4x 99+ P Type here to search End PgUp PgDn PrtScn Home

Shipra Manufacturing Company is thinking about development of a strong charge producing measure by adding one-ton limit during heaters. Each clump (one ton) of charge should go through 30 minutes of heater time, including stack and dump tasks. In any case, the heater potential use factor is just 80% because of stream limitations in different pieces of the framework. Required yield for the new design is to be 16 tons for each shift (8 hours). Plant (framework) proficiency is assessed at 50% of limit. (a) Determine the quantity of heaters required. (b) Estimate the percent of time the heaters will be inactive.

Engineering materials can be classified as being either metals or nonmetals. Medals can be subdivided into Ferris and nonferrous metals and Ferris metals can be divided into plain carbon steel, alloy steel, and cast-iron.
