Data
Figure 2 shows the most important geometric dimensions (in centimeters) of the implant, as well as the most risky and problematic sections from a structural strength perspective.
To simplify the analysis, the resistant sections will be assumed to be circular. The load will be assumed to act at the midpoint of the cylinder, as shown in Figure 2, with an additional safety condition of five times the person's weight. The person in question weighs 894 N (approximately 91.2 kg).
The characteristics of the possible materials to be used are found in Table 1. Note that Chromium-cobalt casting has a different behavior in compression and tension.
Determine
The maximum and minimum stresses, as well as the shear stress, to which the part is subjected in the A-A plane. Assume it is a cylinder with a diameter of 12.7 mm.

- A cylindrical pin made from 1010 steel and a diameter of 0.188 inches is partially placed in a bushing as seen in the image. The bushing is rigid and does not move. If a 50 lb weight is dropped on the 0.2 inch end of the pin, how high up does the weight have to be dropped from to cause the pin to yield?

The water level is 2.5 m above the outlet. The tank air pressure above the water level is 250 kPa (absolute), while the atmospheric pressure is 100 kPa. Neglecting frictional effects, determine the initial discharge rate of water from the tank.

The tank water surface is open to the atmosphere, and a sharp-edged 10-cm-diameter orifice at the bottom drains to the atmosphere through a horizontal 80-m-long pipe. The total irreversible head loss of the system is determined to be 1.500 m. In order to drain the tank faster, a pump is installed near the tank exit. Determine the pump head input necessary to establish an average water speed of 6.5 m/s when the tank is full. Disregard the effect of the kinetic energy correction factors.
