The pressure drop in a duct is to be measured by a differential oil manometer. If the differential height between the two fluid columns is 5.7 inches and the density of oil is 41 lbm/ft^3, what is the pressure drop in the duct in mmHg

The y form of iron is known as: a) ferrite b) cementite c) perlite d) austenite

The force on a cutting tool are 2600n vertically downward and 2100 horizontal. determine the resultant force acting on the tool and the angle at which it acts.

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.
