The hydraulic cylinder shown in the figure has a 2-in bore and is to operate at a pressure of 1500 psi. With the
clevis mount shown, the piston rod should be sized as a column with both ends rounded for any plane of
buckling. The rod is to be made of forged AISI 1030 steel without further heat treatment resulting in yield
strength of 37.5 kpsi, and Young's modulus of 30 mpsi.

The figure below shows a boat propeller mounted on a drive shaft with a 7 mm diameter (d) cylindrical drive pin inserted through the hub
and the shaft. The drive shaft diameter, D, inside the hub is 69 mm. The pin is made from AISI 1020 cold rolled steel, which has a yield stress
of 427 MPa and an ultimate stress of 621 MPa. If the drive pin is subjected to an overload (e.g. strikes a log), calculate the torque (Nm)
required to shear the pin.
Note: Assume that the max shear stress of the pin material is approximately equal 82% of the ultimate tensile stress.

Answer:
PROBLEM:1 A gas engine valve spring is to have a mean diameter of 55 mm. The
maximum load it will have to sustain is 584 N with a corresponding deflection of 7.18
mm. The spring is to be made of tempered wire. Since the material is to be subjected
to repeated loading and fatigue must be considered a low working stress of 650
N/mm? will be used. Find the size for wire and number of coils used. Take modulus of
rigidity as 0.84 x 105 N/mm? .Assume the spring coil is squared and ground. Take
shear stress Concentration factor as 1.15.
