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.

A hemp rope L=12 m long and d=42 mm in diameter is supported from one of the roof beams in a gymnasium. Three gymnasts climb this rope together. The lead gymnast has a mass of m1=50 kg, the next gymnast has mass m2=75 kg, and the trailing gymnast has mass m3=50 kg. Determine the maximum stress in the rope (omax), and the stress in the rope at a location between the intermediate and trailing gymanst (023).
A shaft is composed of elements made of S355 with a modulus of elasticity of 2.1×1052.1×105 N/mm² and a Poisson's ratio of 0.3. As shown in the picture, on the right side, there are two forces of 10,000 N each, acting at an angle of 15° upwards, creating a moment that is statically compensated by the force F2 on the left side. The shaft is supported at positions A and B. In the same position (for simplicity), there are two critical cross-sections leading to stress concentrations. The sleeve near F2 is shrink-fitted. The dimensions there are d=50 mm, D=120 mm, and the length of the sleeve is 50 mm. Ha=1 µm and Hn=1 µm. The fit is H7/s6. Determine breell.
A cable is enacting a force, F, on a built-in hook at an angle 9 as shown in the figure. Determine the displacement of the point at which the force acts, in the direction of the cable if the shaft of the hook has a length L, radius r and elastic modulus E. Ignore the deformation of the circular hook. If E= 200 GPa, F = 50 kN, 0 = 25°, L = 1 m, r- 100 mm: Answer: 8 = 0.196 mm
