a) Determine state of stress at all points (a, b and c). These points are located on the exteriorsurface of the beam. Point a is located along the centreline of the beam, point b is 15mmfrom the centreline and point c is located on the edge of the beam. Present yourresults in a table and ensure that your sign convention is clearly shownb) Construct Mohrs circle at this point andcalculate the principal stresses and maximum in‐plane shear stress (τmax) at pointc. sketch the resulting state of stress at this point clearly indicating themagnitude of the stresses and any angles associated with the state of stress (principal ormaximum in‐plane shear).

- The average heat transfer coefficent for airflow over an odd shaped body is to be determined by mass transfer measurements and using the Chilton-Colburn analogy btwn heat and mass transfer. The experiemnt is conducted by blowing dry air at 1 atm at a free-stream velocity of 2 m/s over a body covered with a layer of naphthalene. The surface area of the body is .75 m^2, and it is observed that 100 g of maphthalene has sublimated in 45 min. During the experiemnt, both the body and the air were kep at 25oC, at which the vapor pressure and mass diffusivity of naphthalene are 11 Pa and Dab=0.61*10^-5 m^2/s respectively. Determine the heat transfer coefficent under the same flow conditions over the same geometry.arrow_forwardAuto Controls Design a PID controller for thefollowing system so that the modified system satisfies the followingspecifications : 1. settling time ,ts = 1.96 s and % Overshoot Mp = 70.7 % Assume a non-dominant pole at s = -15 to solve the problem The plot the compensated andThen plot the uncompensated system in MATLAB. what can you see from the plot ? what is your observation ?arrow_forwardAuto Controls The figure is a schematic diagram of an aircraft elevator control system.
