Answer 1

Question

Chapter 7, Problem 7.3P

Interpretation Introduction

Interpretation:

To calculate the stress in a wing component on an aircraft when fracture will occur at the crack length of 6 mm.

Concept introduction:

Stress can be calculated by plane strain fraction toughness.

KIC=fσπa

Where,

f=geometry factor of flow and specimen. σ=applied stress a=Flaw size( crack length )KIC=Fracture toughness

A short brass cyclinder (denisty=8530 kg/m^3, cp=0.389 kJ/kgK, k=110 W/mK, and alpha=3.39*10^-5 m^2/s) of diameter 4 cm and height 20 cm is initially at uniform temperature of 150 degrees C. The cylinder is now placed in atmospheric air at 20 degrees C, where heat transfer takes place by convection with a heat transfer coefficent of 40 W/m^2K. Calculate (a) the center temp of the cylinder, (b) the center temp of the top surface of the cylinder, and (c) the total heat transfer from the cylinder 15 min after the start of the cooling. Solve this problem using the analytical one term approximation method. (Answer: (a) 45.7C, (b)45.3C, (c)87.2 kJ)
