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

Aflywheel accelerates for 5 seconds at 2 rad/s2 from a speed of 20 rpm. determine the total number of revolutions of the flywheel during the period of its acceleration. a.5.65 b.8.43 c. 723 d.6.86

Water in a partially filled large tank is to be supplied to the roof top, which is 8 m above the water level in the tank, through a 2.2-cm-internal-diameter pipe by maintaining a constant air pressure of 300 kpa (gage) in the tank. if the head loss in the piping is 2 m of water, determine the discharge rate of the supply of water to the roof top in liters per second.
