Problem 3: Astronaut testing At its Ames Research Center, NASA uses its large 20-G centrifuge to test the effects of very large accelerations (hypergravity) on test pilots and astronauts. In this device, an arm 8.84 m long rotates about one end in a horizontal plane, and the astronaut is strapped in at the other end. Suppose that he is aligned along the arm with his head at the outermost end. The maximum sustained acceleration to which humans are subjected in this machine is typically 12.5g.

a) How fast must the astronauts head be moving to experience this maximum acceleration?

b) What is the angular velocity ω of the arm?

c) What is the difference between the acceleration of his head and feet if the astronaut is 2.00 m tall?

Problem 3: Metal Hardness Testing The manufacturer of hardness testing equipment uses steel-ball indenters to indent metal that is being tested. However, the manufacturer thinks there might be a difference in hardness reading when using a diamond indenter. The metal specimens to be tested are large enough so that two indentations can be made. Therefore, the manufacturer wants to use both indenters on each specimen and compare the readings. The order of the indentations will be random. This particular design...

Problem 20-04A a-c (Video) Blossom Company uses a job order cost system in each of its three manufacturing departments. Manufacturing overhead is applied to jobs on the basis of direct labor cost in Department D, direct labor hours in Department E, and machine hours in Department K. In establishing the predetermined overhead rates for 2020, the following estimates were made for the year. Department D E K Manufacturing overhead $959,000 $1,500,000 $720,000 Direct labor costs $1,370,000 $1,250,000 $450,000 Direct labor...
