Determine the minimum diameter of a solid shaft under a bending moment of 100Nm and a torsion of 300Nm if the material has a yield strength of 350MPa. Assume a factor of safety of 2 for the maximum shear stress failure theory.

What precautions should you take to prevent injuries when dealing with heavy loads?

Derive the correction factor formula for conical nozzle i=-(1+ cosa) and calculate the nozzle angle correction factor for a nozzle whose divergence hal-fangle is 13 (hint: assume that all the mass flow originates at the apex of the cone.

Describe one experiment in which the glass transition temperature and melting temperature of a totally amorphous thermoplastic material can be determined. show the relevant experimental results in a diagram which should be properly annotated with the two temperatures clearly marked. what is likely to happen to the curve in the diagram if the amorphous polymer is replaced by a thermosetting type?
