Amultiple plate clutch, needs to be able to transmit a torque of 160 n. m. the external and internal diameters of the friction plates are 100 mm and 60 mm, respectively. if the friction coefficient between rubbing surfaces is 0.25 and pmax = 1.2 mpa, determine the total number of disks required, and the axial clamping force. state all assumptions made.

If a particle moves along a path such that r : (3 sin t) m and ? : 2t rad, where t is in seconds. what is the particle's acceleration in m/s in 4 seconds? a)- 16.43 b)- 16.29 c)- 15.21 d)- 13.79

During a steady flow process, the change of energy with respect to time is zero. a)- true b)- false

Amixture of slurry and mud is to be pumped through a horizontal pipe of diameter 500 mm. the fluid behaves as a bingham plastic with a yield stress of 30 pa and viscosity 0.04 pa.s. describe the effects of the shear stress through a transverse section of the pipe by plotting the variation in shear stress and velocity profile: (i) just before the slurry starts to move (ii) as the slurry flows when the pressure gradient is double that in part (i)
