The final strength of a composite material depends on which of the following? a)- the properties of the individual components b)- the orientation of the various components c)- the ratio of the individual components to each other d)- all of the above

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 sum of the normal stresses does not change as the stress state rotates through an angle. a)-trune b)- false

The process in which the system pressure remain constant is called a)-isobaric b)-isochoric c)-isolated d)-isothermal
