Determine the share (proportion) of person-trips by each of two modes
(private auto and mass transit) using the
multinomial logit model and given the following information:
Utility function: Uk = Ak - 0.05 Ta - 0.04 Tw - 0.03 Tr - 0.014 C
Parameter Private Auto Bus
Ta = access time (min.) 5 10
Tw = waiting time (min.) 0 15
Tr = riding time (min.) 25 40
C = out-of-pocket cost (cents) 150 100
Calibration constant, Ak 0.01 0.07

Adouble-strand no. 60 roller chain is used to transmit power between a 13-tooth driving sprocket rotating at 300 rev/min and a 52-tooth driven sprocket. a) what is the allowable horsepower of this drive? b) estimate the center-to-center distance if the chain length is 82 pitches. c) estimate the torque and bending force on the driving shaft by the chain if the actual horsepower transmitted is 30 percent less than the corrected (allowable) power.

Consider a large isothermal enclosure that is maintained at a uniform temperature of 2000 k. calculate the emissive power of the radiation that emerges from a small aperture on the enclosure surface. what is the wavelength ? , below which 10% of the emission is concentrated? what is the wavelength ? 2 above which 10% of the emission is concentrated? determine the wavelength at which maximum spectral emissive power occurs. what is the irradiation incident on a small object placed inside the enclosure?

Explain the strain-hardening phenomenon on the basis of dislocation - dislocation strain field interactions. also, briefly describe what generally happens to the ductility of a metal that has been strain hardened (i.e. does strain hardening make a metal more ductile or
