Determine the output torque Top, the speed reduction ratio of the transmission R, the tangential loads imposed on each gear, the reaction forces at the bearing locations I, II, III, and IV in the y and z directions, and the torque that must be applied to the transmission house supports in order to maintain static equilibrium.

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

Afan that can provide air speeds up to 60 m/s is to be used in a low-speed wind tunnel with atmospheric air at 35 c. if one wishes to use the wind tunnel to study flat-plate boundary layer behavior up to reynolds numbes of re 10, what is the minimum plate length that should be used? at what distance from the leading edge would transition occur if the critical reynolds nurnber were rer,e = 5 × 105?

Aload of 10kn is to be suddenly applied to the free end of a vertical rod of length 500 mm, the upper end being rigidly fixed. 190 mechanical science what should the diameter of the rod be if the maximum stress in the rod is not to exceed 100 mpa? the tensile modulus of the rod is 205 gpa.
