Question

MINI PROJECT on Frame-type Screw Press A 50 kN capacity frame-type screw press for general usage is to be designed. The preliminary specifications have been established as shown in the figure. The spindle is to be made of high quality carbon steel with a yield strength of 40 kg/mm$^2$, the nut is made of phosphorous bronze. The 4 tension bolts (A) are made of steel grade 30 with yield strength of 30 kg/mm$^2$ and elasticity modulus of 200 GPa. You are required to calculate: Diameter of the spindle. Height of nut. Diameter of tension bolts (A) if the allowable elongation is 0.75 mm.
