1. A cantilever of square cross section as shown was made of mild carbon steel SAE 1020, as rolled, and was designed to support a static load W = 15 lb. After the beam was installed, it was discovered that the weight W was not static but vibrated, so that actually the beam was subjected to a repeated load. Measurement showed that the weight rose and fell a distance h equal to 0.05 inch. Shortly thereafter the beam fractured at the fillet which had a machined radius of 1/32 in. (a) Make calculations to show and state your conclusion whether or not the beam should have been expected to fail. (b) for the same data, design a new cantilever with the same dimensions except with a fillet radius r= 1/8 in. Determine whether a carbon steel would be necessary, and if so, its SAE or AISI no. 1/2" 3/4". 6"

Q1. Design and draw a protective type of cast iron flange coupling for a steel shaft transmitting 'P' kW at 'N' r.p.m. and having an allowable shear stress of 40 MPa. The working stress in the bolts should not exceed 30 MPa. Assume that the same material is used for shaft and key and that the crushing stress is twice the value of its shear stress. The maximum torque is 25% greater than the full load torque. The shear stress for cast iron is 14 MPa.
