A bimetallic torsion bar consists of a steel core (Gs 75 GPa) of diameter di 25 mm around which is bonded a titanium sleeve (Gt 45 GPa) of inner diameter di 25 mm and outer diameter do 40 mm. (a) If the maximum shear stress in the steel is 50 MPa, what is the total torque, T, applied to the bimetallic bar

Fluids at rest possess no flow energy. a)- true b)- false

Adouble-strand no. 60 roller chain is used to transmit power between a 13-tooth driving sprocket rotating at 300 rev/min and a 52-tooth driven sprocket. a) what is the allowable horsepower of this drive? b) estimate the center-to-center distance if the chain length is 82 pitches. c) estimate the torque and bending force on the driving shaft by the chain if the actual horsepower transmitted is 30 percent less than the corrected (allowable) power.

The higher the astm grain size number, the finer the gran is. a)-true b)-false
