Clutches, Brakes, Couplings, and Flywheels

The clutch is described as a machine element used to connect or disconnect two shafts together to transmit torque or power. The clutch works on the principles of friction. The clutch is commonly used in automobiles to transfer power from the driving shaft to the driven shaft.

Question

Could you please help me with these questions

A train having a mass of 15 tonne is brought to rest when striking the buffers at a
terminus. The buffer consists of two springs in parallel, each having a spring constant of 120
kN/m that undergo a compression of 0.75 m when the train strikes the buffers. Find: a) the
strain energy gained by the buffers, and b) the velocity of the train at the instant it strikes the
buffers. Explain the effect on the system if the velocity at the time of contact with the buffers
is increased by 10%.
2 The rotor of a ship's engine may be approximated as an effective mass of 60kg with a
radius of gyration of 140mm and rotates with an angular speed of 3000 rpm. The rotor is
centrally placed between horizontal bearings as shown below:
0.4 rads¹
If the bearings are 2m apart, and the rotor is centrally placed between these bearings, what
will be the reactions at each of the bearings as a result of the ship turning with a rotation
speed of 0.4 radians per second?

Question 2 You are a biomedical engineer working for a small orthopaedic firm that fabricates rectangular shaped fracture fixation plates from titanium alloy (model = "Ti Fix-It") materials. A recent clinical report documents some problems with the plates implanted into fractured limbs. Specifically, some plates have become permanently bent while patients are in rehab and doing partial weight bearing activities. Your boss asks you to review the technical report that was generated by the previous test engineer (whose job you now have!) and used to verify the design. The brief report states the following... "Ti Fix-It plates were manufactured from Ti-6Al-4V (grade 5) and machined into solid 150 mm long beams with a 4 mm thick and 15 mm wide cross section. Each Ti Fix-It plate was loaded in equilibrium in a 4-point bending test (set-up configuration is provided in drawing below), with an applied load of 1000N. The maximum stress in this set-up was less than the yield stress for the…
