Amulti-plate clutch connects two in-line shafts, through 4 plates on the driving and 3 plates driven shaft. the plates have inner and outer diameters 120 and 180mm respectively, with coefficient of friction between the plates of 0.28. the clutch transmits 9 kw at 750 rev/min determine: a)- the axial force between the plates b)- the pressures at the inner and at the outer radi c)- the included angle of a cone clutch that would transmit the same power with the same axial force

If you were designing a bumper for a car, would you prefer it to exhibit elastic or plastic deformation? why? consider the functions of a bumper in both a minor "fender-bender" and a major collision.

Asingle-geared blanking press has a stroke of 200 mm and a rated capacity of 320 kn. a cam driven ram is assumed to be capable of delivering the full press load at constant force during the last 15 percent of a constant-velocity stroke. the camshaft has an average speed of 90 rev/min and is geared to the flywheel shaft at a 6: 1 ratio. the total work done is to include an allowance of 16 percent for friction a) estimate the maximum energy fluctuation b) find the rim weight for an effective diameter of 1.2 m and a coefficient of speed fluctuation of 0.10

Determine whether or not it is possible to compress air adiabatically from k to 140 kpa and 400 k. what is the entropy change during this process?
