part a) A Vernier caliper is capable of measuring to the accuracy of +.001 inches O True O False Part b) The discrimination of a standard micrometer is inches, and the discrimination of a Vernier micrometer is inches.

V) Calculate the speed of tip of the mower blade assuming that it rotates at a standard 3600rpm and has a diameter of 24 inches. Considerng the velocity calculated of a rock flung by the mower was 400ft/s, Does the mower blade tip speed make sense? Why or why not?

Show the mass of a flywheel needed to keep a machine’s speed within specified limits.

Joe takes his little brother Andy down the the playground for an afternoon out. Andy would like to ride the seesaw, but the difference in their sizes, Joe weights 160lbs and Andy weighs 641lbs, makes this difficult. Joe sees a solution from his engineering class and moves the fulcrum from the middle to a new place. The seesaw is 3.5m long. After Joe moved the fulcrum how long was the seesaw on Joe's side?

2. You wish to lift a 15,000 lb stone by a vertical distance of 25 ft. Unfortunately, you can only generate a maximum pushing force of 2,500 lb. a. Sketch the diagram representing the problem b. What is the amount of work you must input in order to move the stone? c. What is the actual mechanical advantage (AMA) required by a machine to complete the work above? d. You build a ramp to create the ideal mechanical advantage. What is the length of the ramp in feet?

It's saying this is not correct. Thank you for your help.

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
