A70mm 6g shaft is to fit a 70mm 4h hole. determine the maximum and minimum clearances determine the upper and lower dimensions of a go-not-go gauge and ring gauge set to inspect the above hole and shaft

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
