Alarge flat plate is dissipating heat uniformly through its top surface due to the embedded heaters. air at 20°c is flowing over the top surface, while the back surface of the plate is well insulated. which estimate, for the surface temperature at the leading edge of the plate, do you think is! reasonable? a) 0°c b) 12°c c) 70°c d) 21°c

Which of the following ziegler nichols tuning methods the response of the controller to a step input should exhibit an s-shaped curve? a)-open loop mode b)-closed loop mode c)-both modes (open & closed) d)-none of the modes (open & closed)

Describe one experiment in which the glass transition temperature and melting temperature of a totally amorphous thermoplastic material can be determined. show the relevant experimental results in a diagram which should be properly annotated with the two temperatures clearly marked. what is likely to happen to the curve in the diagram if the amorphous polymer is replaced by a thermosetting type?

For a gate width of 2 m into the paper, determine the force required to hold the gate abc at its location.
