The truss shown below carries an ultimate load, p* = 40kn. analyse
the truss and determine the member forces in all members. determine
the maximum tension and compression forces carried by the
truss.

Explain the difference laminar and turbulent flow. explain it with the shear stress and the velocity profiles.

Aplate clutch has a single pair of mating friction surfaces 250-mm od by 175-mm id. the mean value of the coefficient of friction is 0.30, and the actuating force is 4 kn. a) find the maximum pressure and the torque capacity using the uniform-wear model. b) find the maximum pressure and the torque capacity using the uniform-pressure model.

Slip occurs via two partial dislocations because of (a) the shorter path of the partial dislocation lines; (b) the lower energy state through partial dislocations; (c) the charge balance.
