Chapter 1, Problem 28P

The mean free path λ of a molecule of gas is the average distance it travels before collision with another molecule. It is given by

λ = C m ρ d 2

where m and d are the molecule’s mass and diameter, respectively, and ρ is the gas density. What are the dimensions of constant C for a dimensionally consistent equation?

Qu 5 Determine the carburizing time necessary to achieve a carbon concentration of 0.30 wt% at a position 4 mm into an iron carbon alloy that initially contains 0.10 wt% C. The surface concentration is to be maintained at 0.90 wt% C, and the treatment is to be conducted at 1100°C. Use the data for the diffusion of carbon into y-iron: Do = 2.3 x10-5 m2/s and Qd = 148,000 J/mol. Express your answer in hours to three significant figures. show all work step by step problems formula material science

In figure A, the homogeneous rod of constant cross section is attached to unyielding supports. In figure B, a homogeneous bar with a cross-sectional area of 600 mm2 is attached to rigid supports. The bar carries the axial loads P1 = 20 kN and P2 = 60 kN, as shown.1. In figure A, derive the expression that calculates the reaction R1 in terms of P, and the given dimensions.2. In figure B, calculate the reaction (kN) at A.3. In figure B, calculate the maximum axial stress (MPa) in the rod.
