Chapter 13, Problem 13.32P
Interpretation Introduction

Interpretation:

The cooling rate at which AISI 9310,4320,1080 having similar hardness needs to be determined.

Concept Introduction:

Hardness is a material property of a metal due to which material resist the plastic reformation. Plastic reformation means material reformation which undergoes non-reversible change. Hardness is a material property to resistance to twisting, scraping or cutting. Hardness is not constant or fixed for all material, but it depends upon strength and plasticity of metal, material hardness is expressed in terms of hardness number.

The rectangular gate shown in figure rotates about an axis through N. If a=3.3 ft,b=1.3 ft, d=2 ft, and the width perpendicular to the plane of the figure is 3 ft, what torque(applied to the shaft through N) is required to hold the gate closed?
The former expert solved the question, but I didn't understand how he simplified the fractions. A communication satellite is in stationary (synchronous) orbit about the carch (assume altitude of 22.300 statute miles). Its transmitter generates 8.0 W. Assume the transmit- ting antenna is isotropic. Its signal is received by the 210-ft diameter tracking parabo- loidal antenna on the earth at the NASA tracking station at Goldstone, California. Also assume no resistive loss in either antenna, perfect polarization match, and perfect impedance match at both antennas. At a frequency of 2 GHz, determine the: (a) power density (in watts/m²) incident on the receiving antenna. (b) power received by the ground-based antenna whose gain is 60 dB.
An elevated tank feeds a simple pipe system as shown. There is a fire hydrant atpoint C. The minimum allowable pressure at point C is 22 psig for firefighting requirements.What are the maximum static head (in ft) as well as pressure (in psig) at point C (i.e. nodischarge in the system)? Do we meet the pressure requirement for firefighting? (Please donot worry about L or d in the figure below)
