Would the state of stress at this critical point be multiaxial or uniaxial? Why?

1. A disk-type flywheel, to be used in a punch press application with 0.04, is to be cut from a 1.50-inch-thick steel plate. The flywheel disk must have a central hole of 1.0-inch radius, and its mass moment of inertial must be 50 in-lb-sec2 .

a. What would be the maximum stress in the disk at 3600 rpm?

b. Where would this stress occur in the disk?

c. Would the state of stress at this critical point be multiaxial or uniaxial? Why?

d. Would low-carbon steel with a yield strength of 40,000 psi be an acceptable material for this application?

Find the gain and phase characteristics of the maintaining amplifier.

A solid-state capacitive humidity sensor has a capacitance given by: C = 1.7 RH + 365pF where RH is the percentage relative humidity. The sensor has an associated parallel resistance….

calculate the mean velocity of the gas at maximum flow rate

A pitot tube is used to measure the mean velocity of high pressure gas in a 0.15 m diameter pipe. At maximum flow rate the mean pitot differential pressure is….
