Assume that you send with Fed-Ex a box of three8mm tapes. These tapes each contain7Giga Bytes. A Fed-Extruck travels in NYC with an average speed of21km/hour. For what range of distances does Fed-Ex have a higherdata rate than a transmission line whose data rate (excluding overhead) is150Mbps

Explain the difference laminar and turbulent flow. explain it with the shear stress and the velocity profiles.

Abrake has a normal braking torque of 2.8 kip in and heat-dissipating cast-iron surfaces whose mass is 40 lbm. suppose a load is brought to rest in 8.0 s from an initial angular speed of 1600 rev/min using the normal braking torque; estimate the temperature rise of the heat dissipating surfaces.

The thermal expansion or contraction of a given metal is a function of the f a)-density b)-initial temperature c)- temperature difference d)- linear coefficient of thermal expansion e)- final temperature f)- original length
