In the process of producing engine valves, the valves are subjected to a first grind. Valves whose thicknesses are within the specification are ready for installation. Those valves whose thicknesses are above the specification are reground, while those whose thicknesses are below the specification are scrapped. Assume that after the first grind, 71% of the valves meet the specification, 18% are reground, and 11% are scrapped. Furthermore, assume that of those valves that are reground, 90% meet the specification, and 10% are scrapped.
a) Find the probability that a valve is scrapped. Round the answer to three decimal places.
b) Given that a valve is scrapped, what is the probability that it was ground twice?

A high carbon steel shaft is used in an engine and subjected to
different loads. In order to
analyse the stress in the shaft, consider a rectangular element
within the material. This
element is subjected to compressive stress of 135 MPa and shear
stress of 166MPa in the
vertical direction. The compressive stress in the horizontal
direction is 176MPa with a shear
stress of 115MPa.
a. Sketch the state of stress on this element.

A six-cylinder engine uses pushrods to actuate the valves. The
pushrods are 8.0 mm in diameter and are 650 mm long. Suppose the
temperature can change from -40oC to 116 oC.
If the pushrods are allowed to expand unrestrained, calculate the
change in length in mm to two decimal places. Assume they are made
from AISI 1040 steel, E = 207 GPa, and have a coefficient of
thermal expansion of 11.3 x 10-6/oC.
If the pushrods were installed with zero...

Conduct the biological evaluation of the bioprosthetic heart
valves as part of a risk management process based on ISO 10993 -1
(Biological evaluation of medical devices — Part 1: Evaluation and
testing within a risk management process). Your analysis should
contain medical device categorization (nature of body contact and
contact duration) and biological evaluation test required for the
device.

In
a certain process, steel bars are manufactured and subjected to a
torsion test. Bars are considered acceptable if they support at
least 15 lb-ft. Currently the process produces bars that support on
average 15.23 lb-ft with a variance of 0.04 lb-ft^2.
a. What proportion of the bars will not be able to meet the
specifications?
b. If we take a sample of 50 bars, how many are expected to
fail the test?
c. If we want no more than...
